Crinkled leaves, I forget what the cause is

Hi guys,

I forget what causes the leaves to look like this. Light, over watering, low nitrogen, low calmag? I’m running coco at 650ppm, ph 6.2, veg cycle, 18/6 light cycle in veg, just transplanted, so maybe transplant shock?

ok i am not a coco grower except i use coco instead of peat in my organic mixes but thats not the same as salt based growing but if i had to give it a go to get the ball rolling i’d say maybe your ph is a little high as i mostly see 5.8-6.0 advised in coco growing.
