Does anyone know if these are pest, deficiency, or light related. My girls are looking good I hate to let something get away from me and lose them all. Or is it cause of genetics
calcium deficiency, either ph was wrong, or nitrogen toxicity blocked calcium. calmag in small doses for 2-3 waterings should sort it and stop using N for a week at least, so no grow nutes.
Some damage looks to be from insects and others look to be nutrient based. Not to worry.
0.75g/day of water is probably a little high, your lights off pic has a lot of droop, so back off that a bit and make sure you’re getting aerated/dry soil between feedings.
