No one answer me, my plants are still yellow but alive

My ph meter showed a very low ph 4 days ago, I just add buster to raise it, but I didnt see a big change, so I put more and more ph up, next day I found out my meter was malfuntioning and it was giving me the wrong lecture and I have raised the ph when was not need for it, as a result my plants are yellow a litle bit, stressed, sick, but still alive... the leaves have spot, some of then burned, some buds look like rape, cause the white hair change to yellow and brown hair, no all but most of the one that are straigh under the lights, I stop the feeding and replace it for water, I feed then just folliar until i be able to get a new ph meter, also I reduce the lights from 1000 to 600 to aliviate my plants stress, now I m looking to help them to heal because they are still alive, I just start week 4 of bloom counting from the day I have changed the lights to 12 hours... I need help and any information will be welcome...

I dont think your gonna get much help with those pics under hps light. We need a true representation of leaf colors etc to help. Whats your relative humidity in the room? What temps are you experiencing with lights on/off? What ppm are you feeding them? What nutes are you feeding it? Coco or hydro? Are you foliar feeding with lights on? Lots of missing info here for someone to try to point you in the right direction. I will say that you should invest in decent equipment if your gonna run crops that size. Dont make much sense to ruin such a large crop over a >$100 meter.

Who grows crops that size and can't even manage basic hydroponic growing techniques .Definately invest in a quality pH meter.

I have use that metter for more than 3 years and I love it, but it was the problem, that I trusted that metter so much because my own experience using it, it is a good metter and I strongly recomend it, even the ph sensor malfuntion the ppm and temperature of the water works fine... it never happen to me before, and this is the reason the accident happen, that is s nice metter and I just take it for granted, maybe with a cheap and a bad metter it never happen because I havent trusted it when it showed the numbers, this metter have a prove with the 3 sensors and only the ph is not working properly... and I going to buy the same one when I have the chance, i know it and I trust it...

When you get on a feeding program you get to know what your feeds come out at.... Ppm and pH wise. If all your feeds are normally in a certain range and suddenly it's way out of wack... Its time to calibrate or double check or something.

For example my feeds always come out at 1.2ec and pH 6.4,it takes exactly 3 drops of PH down to put me at 6.1 where I like to be.

I can duplicate this every single time. If my meter suddenly said pH was 4.8 well then I'd have to suspect a problem with the meter and do some checking...

The humidity is between 40 and 55, it is a sealed room, the CO2 at this time was 1200 to 1300 ppm, the temperature with lights on goes around 75F and with lights off around 70F, at this moment the ppm in the mix was 1230, Im using the Maxi series from GH, I follow the feeding chart for that line but I keep my mix maybe 15% lower than what they recomend and I just do a couple folliar sprays using xnutrients, the ph in the reservoir is between 5.7 and 6.3 I mean this is the far I let move it before I adjust it. I have 45 gallon reservoir that I fill it with half tap water from the city system and the another half is from the AC and Dehumidifiers.... I have a 45 gallons reservoir but I calculate nutrients to 35 gallons, if not the mix will be to high, I clean every week the tank letting the system run one day just with water and that water day I use to add any insecticide or antifungal, like atak or ms-90 or peroxide, if I going to use one depend the situation... my plants have a nice separation because I open them the most I can to get more size using two nets on then... I made thoses one a litle shorter because but wide cutting the top several times when growing but they were so bushy that I have the need to desfoliate them a couple times, to many branches and to many leaves that were pushing eachothers inside the plants... I use 6 hps lamps 1000 W with cooling system that I can touch them with no problem, everything is fine, but I just have that isue with the meter and the ph high... I wil try to get some pics as soon they wake up at 7pm, the thing is I will take the pic with my phone cause I cant use the computer to load pics from the camera, but soon I will, I unserstan what you said about the 3 drops to raise o lower the ph level, but three drops are far from what I use, when I feel my tank, mean my reservoir, after next day I have to add 10 gallons of water everyday to the tank, everyday when the lights go on, the level of the mix in the tank is about 1/4 lower, the ppm of the mix higher around 1400 and the ph low around 5.7 more or les, so I just add water 10 gallons and that is it, the water low the ppm and raise the ph... depend how is the water this day, because here the ph in the water in winter have a big diference than in summer, also today could be 7.0, but tomorrow will be 6.5 and next day almos 7.5 or even more, when I mix the new food at the begining of the week, sometime I dont even need to use ph busters at all, because cilica and calmag raise it first more than 8.0 but the nutrients put it back to a nice level, 6.2, 6.3, and I know it use to go down.... i think I m writing to much and you have no idea how hard is for me to write in english... im apologise for my english but im trying very hard to explain the best i can for you to have a better idea of what going on here.

I dont know why did you said it, what are basic hydrophonic tecniques for you?, because the only problem I was talking about was about my ph raise for a broken sensor in my hanna meter, but the ppm and water temperature sensor work fine, so I didnt have an idea that a meter that is able to give me these 3 lectures was malfuntioning in just one of them, and the ph sensor give me false numbers and I ad ph up buster to the mix# when the ph was high already... and at the same time I have done some folliar the day before with a product that I never use it before and I though that this priduct when driping in my buckets and moving finally to the tank could be the reason of the droping of the ph Ievel... also I have used to grow crops bigger than that, and I have been doing it from 1993, when living in jamaica and the metter was a lamp or litle papper strips with a matching color chart, that was an accident and I share it here looking for something that I dont know, maybe a product or an advice, I dont pay attention to a negative criticism like that one, I just passed by them and moving on... I can do crops 4 time bigger than it with not need of any meter... and I dont need a negative opinion of what is in the pass, I was looking for an advice, and if that person who try to show himself like a master grower and is no able to help with an advice but spent time to criticize and to create a false statement of someone that he didnt know... I m not impresed about it, I just dont care.

I m new here, and I have seen in the button of the coments, that people like that coment...I did like some coments but I didnt find a way to say it, not like button nowhere... do someone can help me to find that button that I supose to click to be able to show my gratitude giving to a coment a LIKE?

This may be suspect as to why your leaves are yellowing and your pistols are looking brown and ripe so early. I recently used a fungicide by the name of "Green Cure" and I mixed it like instructed on the label. 6 hrs later my lovely young budlings went from fuzzy white pistols to scraggly brown hairs just like you described. After re-reading your post and what you stated in your last post, I think this may be your issue.
Before my foliar spray:

6 HRS after foliar spray:

Luckily I was forewarned about this happening so I didnt freak out, but it still bothersome to see. Necessary none the less.
Im wondering if this is what has browned your pistols and burned your leafs. What was it that you foliar sprayed on it and what were you spraying for? Also, did you do it when the lights were on? Spraying with the lights on is a sure way to get burn spots and leaf discoloration over night. Though your ph may have been waaay off,I just dont see pH doing anything to that extreme that quickly.

Ty, I know it now, I just get it... I was worry about it, but I have earned it a minute ago. Ty

They are no eating that much like they use to, I m worry about to get strong reduction in my harvest, but the only way I will find out it is waiting till the end.

Well it is strange that after how many weeks of adding the same amount of everything your ph suddenly started to drop and you didn't suspect the meter or calibrate it......it is strange.....sorry if you took offence. If my readings suddenly change the first thing I check is calibration then try and fix the issue. Have you checked your roots?

A couple weeks ago the temperature here where I m living raise big time in the day time, tha is night time for my grow, my AC cant be able to deal with it and for that reason I have a litle high temperature and humidity when my plants were sleeping, it bring to me some white powdery mildew that i found in some lower fan leaves, I cleaned it with vinegar dilute in water, I put plastic bags covering the buckets to prevent that vinegar reach the reservoir, but it drip there anyway, for that reason the ph # decrease to 5.3, another reason is the water, the system water here is coming low now, around 6.5.... sometime is 7.0, sometime more... I did a folliar spray the night before the accident happen with SM-90 to try to eliminate any trace of the fungus and taking advantage that I was not deep in flowering yet. Next day the accident happen when I read the ph level low I guess was the SM-90 that filter to my tank and I add some buster to raise it, but SM-90 raise it instead of lower it, at this time was the metter fault, I supose to do what you said but to many things happen that have confused me and also my blind trust on the metter that give me an acurate reading for a long time and still is giving me the ppm and temperature of the water...
I have no way to se my roots, they are inside the buckets but with my system I have never experimented any problem with roots and the roots that scape from the bucket botton I just cut them off before they block the chanel where the water return to the reservoir... but I believe they are ok... I will take a pick of my system right now, my reservoir is very low and wide, just 3" tall, and the chanels are on it, and the buckets are on the chanels, the bucket have two holes in the botom that let the water drop in the chanel that bring the water back to the reservoir, and that water is pumped back to the plants by pvc pipes, hoses and feeders, my water is moving all the time, rotating by the system and is the plants choices drink it or not... with that movement the mix is always oxigenated and clean...

I have show my meter manual, now someone have to tell me if it is a decent meter or not, if not tell me what is a decent meter? I paid more than $200 for it and it works fine until the ph sensor stop working, maybe I drop it, i really dont know... how someone can talk about my meter without knowing what meter I have? I supose to ask first and after I know it, so i will talk... precipitation and it is not rain.
Mercedes Benz, Rolls Royce, and Moon Rockets need to be fixed, why?
Maybe thoses are no decent machines.

I actually bought a cheap Chinese one last year and it's been as good as my other brand name ones, could have gotten lucky. Also I do calibrate once a week or if I think things are getting out of whack. And sorry, didn't mean to criticize but you should get into the habit of testing your meter. My EC meter has never been calibrated but I use it more for reference than actual measuring.

I feel bad not because of the calibration, but for the reason that 2 people said that I supose to invest in a decent meter when no one know or ask what meter I have...

Mercedes, Rolls, Ferraris, even moon rockets have their final day too

to tell you the true, I order one of thoses yellow meters that they have 50 names but all are the same and I cant use it, it jump from 7.0 to 8.9, also I got water from the pipe and put it in 2 cups and it give me two diferent number for the same water... maybe my was the only bad one but I give it away, it was so cheap that I dont even bother myself in return it.. crap...

I had one of those and it created more problems than it alerted me to. Dont dare let the probe end get even the slightest bit dry for longer than 15 minutes either. Lesson learned for me. I bought HM meters which are not expensive, but after 1.5 years and many weekly calibrations they are VERY trustworthy. Not to mention like @Budley Doright mentioned in a previous post, after so long of mixing the same nutes in the same systems with the same tap water you really do get a feel for where it should be and if the numbers are off , the first thing I will do is check my meter. I could almost get away with not even using meters at this point.
