Started to feed every 48hours and slightly dropped the nutrients to see if it helped with these claw looking leaves, no change so far. On to next week.
Hi there,
Looks like a common problem known as "The Claw" A Nitrogen toxicity is the result (usually from too high levels of nutrients overall) Although, could also be a sign of overwatering or wind burn. It's hard to tell.
I would cut back on your nutes and maybe try longer durations between feeds or lower the amount of water to see if this clears things up?
I hope this helps.
