I need help identifying this leaf curl. I usually assume leaf curl is a watering problem, but this one is different.
This is a clone of THC Bomb, vegging outdoors, hot summer, organic soil, curled leaves in multiple spots but new growth is OK. The mother plant is not showing this problem. I water every other day with pH around 6 - 6.5, have given it light nutrients and magnesium. No calcium added but lots of gypsum in the soil.
Does anyone recognize this?
