phosphorus or cal mag defeciency late veg (((pics included)))

[igotmunchies]

growing in a 5 gal smart pot
coco/perlite mix
general hydroponics maxi series (dry nutes mix)
2.5 ml gh gro
1.25ml gh bloom (transitioning to bloom)
1ml rapid start root hormone
1ml floralicious plus
2ml diamond nectar
1ml liquid koolbloom
1ml florablend tea

is what ive been feeding it at 5.8 ph. runoff is usually 5.8 - 6.0 and has never been above 6.1.

1000w hps in a tent. temps 76-78 in day and 72-74 at night


i water every other day with tap water nutrient solution and flush every 4th watering. just flushed before i took the pics actually. all the water i use is evaporated for at least 5 days if not a week.

could it possibly be calcium and magnesium defeciency, cuz if so i can easily add some cal mag, if not im not sure why the phosphorus is getting locked out. there should be ample of it in the mix. any suggestions would be greatly appreciated thanks

Phosphorus I'd say from pictures I've seen on one of the sticks from this part of the forums here at r.i.u. U know I'm always second guessing what I think again and again but yea from the pictures I'd def say phosphorus, check out the pics and wait for some more advice as its better for afew heads to take alook than one lol ill keep following to see how it works out hope its sorted soon my friend scunkworm

 

[beuffer420]

I gotta go phosphorus as well.

 

[silasraven]

3rd times a charm, its phosphorous

You have a few things going on here that you can easly fix and save your plant. First, your in coco so CalMag should be given with every feeding. Second, Your throwing the plant off by flushing it time and time again. Third, your plant is hungry! I'm not sure what your ppm level is when your feeding but I'm going to guess it's low. I would start correcting the issues by making a good VEG food batch and add CalMag to it then feed until you get a good run off going. If you flower in the next few weeks before you fix the issues, your not going to have a good time my friend.

 

[igotmunchies]

Ok thought so. But why??? Lol. And more importantly how do I fix it. I'm bout to switch to flower tomorrow but I don't want to start with my baby in bad shape

First off, nice post, with good info.
To me, it looks droopy, I would guess due to overwatering since you gave some nice numbers for temps, and yes, a P deficiency, but it also looks hungry for N, unless that's just your lighting making it look really pale.
Here's a couple charts you can copy and save for future reference.

I heard that but when I added in cal mag it messed stuff up a month ago. I think my water has a good amount of calcium in it plus the GH maxigro is 10-5-14... 6% cal 2% mag. And thui last week ive been mixing in the maxibloom which is 5-15-14 5% cal amd 3.5% mag. Its not supposed to need it. But yeah were definitely on the same page that this needs to be fixed before I flower her.

How can I fix this P issue so I can flower before this plant runs into my lights haha

Some LST will bring down your height, you can veg another few weeks, and you'll get more tops.

i would have to agree with 12, but only to a certain degree. 1st off, you do have multiple issues.

secondly, i would up the ph in your mix, because it seems like that ph isn't working for that plant, which can explain why the plant isn't up taking phosphorous and what looks like salt damage on the leaves.

lastly, i would flush with and foliar with a light dose of cal/mag to get the plant back on track. once you do that and your ph is in range, i would feed how i normally would (without cal/mag) and watch for any cal/mag issues to determine if you actually need it. reason being, if i am not mistaken, the maxi series is a one part and shouldn't need any cal/mag. however, if it does (due to coco) you should need very little cal/mag and not at the recommendation that most tend to recommend.

Your roots will only take what the plants need. From the pictures you have posted, It looks like your plants are not being feed enough. When your not feeding enough and then your add a flush on top of it....So what you need to do is stop flushing. You need to give the plant a strong feeding and let is settle for a week to recover. Flipping a plant in that shape is not a good idea my friend. The energy a plant takes in the first two weeks of flower is way more then your plant can offer right now. You need to find a balance with veg nutrients and also feed it CalMag. You also need to let the plant rebound and recover. If you don't give the plant time to recover from the stress it is going threw now, just think what kind of stress your plant will have to deal with in flower.

Awesome that sounds like a perfect plan. Can I mix some floralicious, cal mag, and koolbloom foliar spray and add 1-2 ml of cal mag to my mix and see how it does. I'll water at 6.1 or 6.2 as well and see if that helps. My runoff will probably be 6.5 cuz GH stuff raises pH over time... is that cool?

 

[Fresh 2 De@th]

tbh, when i comes to foliaring spraying, i don't use too much. i like to keep it as simple as possible. i would do all but the koolbloom and a ml of cal mag with a drop of floralicious + per liter of water.

 

[12n12]

Fresh also made some good points. I'm not sure about the PH but now that I look, it could very well play a issue. I have never grown with a PH higher then 6.0 unless I'm in flower. I use pro mix and coco and 5.8-5.9 is pretty much my target PH level. I can tell you when it comes to coco, you will always need to feed with CalMag.

my gut says heat, too much water, a cal mag foliar spray and bloom nutrients will bring em back to form.

 

[igotmunchies]

Cool. Too late on the foliar spray I added 2 drops of koolbloom, 4 drops of floralicious and 1ml of cal mag to 1L spray bottle. Mixed up a a full tsp of GH grow even though they only recommend .5 along with all the micronutrients. 2 ml cal mag 2 ml diamond nectar 3 ml florablend 2 ml koolbloom and 1ml floralicious. you're right my plant is 2 months old and a monster so underfed is probably correct and so is cal mag.

I guess the only thing I can do now is wait a couple days and I'm gonna start watering every day instead of 2 days cuz I heard bad things happen if coco gets close to dry.

 

[Fresh 2 De@th]

i hope that was in a gallon of water and you added a wetting agent to that mix before foliaring.

also, dilute that mix to around 400 ppms or less to be on the safe side.

 

[igotmunchies]

I foliared it with only a few drops in the liter. The other measurements were per gallon for what I watered it with. Watered with 3 gallons like that

i would definitely suggest letting the coco dry out a fair amount between waterings.

K so every other day like i have been then? Other than feeding it more and adding a little cal mag to the mix and waiting for it to recover before I flower is there anything else I should do?
