Diagnosis help!!

I'm using GH Flora series with their "light" feed schedule. Currently starting week 3. EC has been around 1.2. Including 5ml p/gal of calmag since I'm growing in coco. PH always between 5.8 and 6.2. Fertilizing twice a day. Been seeing this issue for about a week and it's getting worse. I flushed and refed at 1.2 EC. Not sure if it's nutrient excess or deficiency. Should I try using the GH Flora "medium" or "heavy" feed schedules instead?

Can't tell for sure because of the angle of the pics, but it might need to be re-potted.
I hope you didn't flush with plain water.

Brownish copperish leaf spots are normally from calcium deficiency. The crinkled leaf structure suggest week cell structure, also often indicates low calcium. Try upping your calmag.

humidity/heat problems
allsoo rule of thumb if the plant leafs are outside the pot it usually means the roots have taken over all or almost all

Hey everyone, thanks for the tips. My intent was to repot it into a different larger pot today

Repot into a size at least double.
Add hope you didn’t flush with plain water.

I usually “ prep “ my larger coco containers ( Mother Earth coco / perlite ) with a 5.8 ph water / calmag to wet the medium - transplant - then 1.2 EC maxigrow .
Those buckets are 2 gallon.
