Key Keffka.I missed this the first time around. This is a classic deficiency sign. I’m gonna tag @Bill284 he may have seen this before.
Are you phing your solution? When and how are you adding your calmag, before or after you mix your nutes?
Thanks for the tag Amigo.
O.P. questions
Are you putting your c.m. in your plain water first , recommend dose?
Mixing it well first.
Then a & b then setting your ph to 5.8 exactly?
Then feeding every day to run off?
Never giving water?
Always keeping your coco wet?
If you are doing those things then it's your coco.
If not you should be.
Your coco its not buffered.
Up your calmag a bit.
Do no remove any more leaves!
Let me know.
Btw Welcome to 420Magazine.
Stay safe
