How to flush?

[o'brother]

If your ppms r 976 check again later and if its dropped she needs more food,if it raises then its drinking more than its eating add plain water. Gotta play with it until it stays pretty steady meaning uptaking equal amounts of food and water. As she matures she will need more food. Just check often and keep adjusting....your meter is your friend!

Wow, Once you hit me in the head with the obvious,It seems so clear. Thank you. Tonight I plan to replace the res with all new solution.I will note the ec from the start.Then monitor. I'm guessing that when food is called for, You only mix the solution strong enough to rais the ec back to the desired levels with enough water to fill the tank. Is that the idea?

What u r reading is a tds measurment represented in ppms. It's all a conversion of conductivity,at what conversion rate is your pen reading 5 or 7?

I believe it is the 5 scale. The results are given in numbers like 800-1500. not like 1.6-3.0. If that does not answer your question correctly,Just say so and I will go learn what I need to to answer your question properly. Thanks for your help.

For example if your reading 1000ppms and she goes down to 800 make it a lil hotter to say 1200. Keep monitoring until u figure out where shes holding steady

I will work at this for a few days and post results. thank you.

Well,The results are differant than I expected.over a 24 hr period, The ec was 976. now 977 The ph was 6.0 now 6.5 and about 5gallons of water gone. My guess is only water is needed with a little ph up. Would mean that at this time 975 is about the correct ppm. Don't be scared to hit me with some more obvious. And thanks, Really.

With your ph at 6.5 in a hydro setup she's not gonna do much more than drink water(depending). I'll try to find an absortion rate chart and post the link. R u flowering?

 

[Oo S0uP oO]

you need to lower ph to 5.8-6.0 Also if your run off is stable ppm, I would top off with 976ppm or not at all remember your trying to leave it there in the sweet spot. -SouPView attachment 2583187 Also rising PH can be attributed to many things (Not soaking your medium with PH'd water before use, Out of range PH nutrients trapped in your system from before the change, Mixing of nutes and many others) Its just something that needs to be kept tabz on over your grow.

+Just up from the grow. had to add 10 gallons of water, got ec to 860. ph to 5.8. I will wait and chech tomorrow. If the absorbtion rate chart you speak of is the one that shows at what ph differant nutes are available I have one.It shows that P is not very available a below 6.5. Is that differant for hydro? If it isIs the whole chart off by the same amt. yes I am flowering. 24 days at 12-12. the second pic shows the only problem plant with some wilt or leaf curl. SOuP- thanks for your advice. I'm doing hydro but I get your drift. When I started this thread my ph was going down, Now it is going up. Seems to hold stable for 4 or 5 days then starts to drift. I will take your advice and keep tabs on it. Thanks guys I will be back.

Do you use Silica in your system??? Possible raise in PH can be cause by the break down of silica salts over time??? Also Are there more than one strains out there on your tables? cause it looks to me that some of those plants seem ALOT more comfortable with what your doing than others. If so, theyre individual demands may inspire you to drop PPMs for a week and see how the room as a WHOLE reacts/ Entirely up to you of course But worth a try IMO-S0uP

Edit. And if its holding stable for 5 days then you just get to change out your res every 5 till the end of this run with no inconvenience but time, NBD!

It sounds like you are reading PPM, you have a PPM not a EC pen,, thats good for the USA. But say PPM of XXXX if you say EC... we go what??

I knew what he meant and so did you, He will learn in time how to convert. Its not like you couldn't have posted the charts yourself right? As you surely don't understand the chemical conversion equation yourself. Fucking Troll. I hate everything you post kid, go play kick ball or something leave this to the grown ups and the ones trying to learn how to provide for themselves without the routine be-ration of misinformation and insult you offer. Thanks from all of us-S0uPView attachment 2583618

I am kinda tied up now, Have visitors. I was able to jump down for a check. ppm last night 860 tonight 950. ph stable 5.8 tank down 2 gallons of 16. I will refill the tank with water only and recheck ppm's. SOuP your dead on correct. I have more than one variety. basicly half Freedom 35 and half Iranian g-13. or pheno of.(totaly another story.) I don't intentionally add silica. if it's not present in general hydroponics, then I don't use it. I will follow your suggestion and let the ppm's drop and watch to see how they react. After checking the nutes as I mixed them, I believe I've been running rather low ppm's but thats an uneducated guess. I think the pen I have is the hanna. It's marked with an H and anM. It indicates TDS and EZ. This is a borrowed one. I have a new one and a ph tester coming this week. Honestly I had no clue to what I didn't know. any thanks to you and the others taking time to help me learn. Teach a man to fish...

Just added 2 gallons of water. res back to full,ppm's 750. ph 5.8...Later.

Hahaha soup,gotta let em know! Good lookn on posting the charts. Obrother,sounds like u r on the right track ya when u find the sweet spot as soup said top with the equivelent amount in ur res to keep it there.

Thanks guys for all the help. got my new pen. I will use this for a while and see what I can work out. You will prob hear from me again. I like learning new things. Later.
