Yeah and i use Jack’s 321 every feeding so it can’t be cal mag right??
Had any issue with coco coir and Jack’s nutrients?
It still can depending on the lights. If you’re running high power they can be more hungry than the regular formula.
I bumped up my cal nitrate to 2.5-2.6 and the Epsom to 1.4-1.5 and it’s helped tremendously
