My CYCO Coco pre-mix was ph buffered. The De-Gnat agent that goes over the coco for mite protection maybe causing.

Nutrient problem??? Excess or deficiency?What do you think is the leaf issue? Open to second opinions. Most everything stayed the same, except: > increased water: 2L to 3L per 7 gal of soil > introduced a bloom booster > increased volume of worm castings, molasses, mycrobes and ethylene to the tea

Leaves curl on upper new growth and mid but not lower.I’m using the canna coco line except boost, looks like phosphorus deficiency. I just lowered my a and b 0.7 ec and added 0.3 of pk for a total of 1.0. Is this phosphorus deficiency and do you think my changes will help. Leaves are a little dark shinny and the shape is odd.
