Help meeee

My flowering Skywalkers are doing this weird thing with their leaves turning a red/rusty color at the edge of the big fan leaves and idk whats wrong, i think it must be the ph of it bc when i measured the runoff it was at 6.8 even tho i water with 5.8-6.4 everytime. I use Coco median, water every 3 days, indoor grow with an average of 80degrees in the room and %50 humidity...

Pleaseeee help meee

also get your heat down...75

I use cutting edge solution stuff and it already has calcium and magnesium in it thooo

ok.....then don't add it

I run in coco with CES using RO water and 7ml of cal-mag per gallon. plants look great. Run off in coco not that important.

That definitely looks like magnesium deficiency, what EC or PPM are you feeding at? Just because your nutes already contain it doesn't mean the plant is getting enough. I use Cyco at a slightly lower EC then recommended and just add cal mag also in early flower. If your run off is 6.8 I would water heavy at 5.7 next time, that's pretty high. Good news is that deficiency doesn't hurt the plant much, just looks ugly.

Some plants require more cal mag than others. There may be a pH imbalance there in the coco IDK coco is overrated and you can get equal or bigger plants in a nice balanced organic soil mix without all the headaches of micromanaging.

your temps are fine 80 is fine just bring it down a little as your flowering progresses.
