Deficiency, toxicity, light stress? Wtf is going on - week 4 flower

[meyoutoo]

Week 4 in flower running 4seasons 200w LEDs dtw in coco perlite 70/30 blend. Lights are about 20 inches away

Top leaves are yellowing and appear to have withered/become skinny. Whereas the majority of bottom growth seems to be okay or at least not as badly damaged

Watering twice a day, just increased to 3 times, with around 15% run off. Have tested run-off both EC and ph coming out as it should

PH is 5.8 and EC 1.8-2 as per recommendation on label

Currently using Green Planet dual fuel Part A+B

Flushed them a week ago which hasn't appeared to have made a difference. Growth has been stunted significantly. Temps have been hovering around 80 F with humidity around 60%


** FYI photos are of 2 different plants, same strain, however one appears to have been affected worse than the other


All help/suggestions greatly appreciated




One frustrated grower!

To me one looks over fed and the other under... But your medium is uncharted territory for me.

Luckily enough we have a very knowledgeable coco person on hand @Bill284, this kind being requires a little assistance .

*Edit* And sorry for the tag.... I just didn't want this one to be bumped to bottom and missed.

Im no expert, but following to learn.

Just wondering why watering 2- 3x in 1 day ?

Good morning Hap
Sorry about your garden @meyoutoo
Just one question, Are you putting calmag in your plain feed water before your nutrients ?
Coco sucks calcium out of your girls.
It's also helpful with nutrient uptake.

Yes it’s your problem.
Add it to your plain water first.
Mix it really well.
Then A.
Then B.
And I always use a kelp , seaweed or b1 product.
Last.
Then check ph and Set to 5.8 exactly.
Then feed to runoff every day.
Always keep your coco wet.
Never any plain water.
That’s a good way to go from now on.
Anything at all you need I’m always available my friend.


Stay safe
