Not sure what’s causing this with my leaves a friend says it’s something toxic in the grow medium but I’ve never put anything into my soil other then nutrients and water and I follow the directions on the bottles , but if I can identify what the cause is I can correct it and it also seems to be affecting one strain more then the rest I’ve included 2 different strains in these pics the first strain Zkittlez and the last two pictures are Tropicana Cookies I don’t know how much that will matter but just in case it does
You can see how in the first couple pictures they look funny to me and it also looks like the leaves are tacoing I guess is what I would call it
They are in a Coco Coir perlite medium I’m using the advanced nutrients line and I follow the directions on the containers except when I first started or add a new nutrient I cut the amount in half and the base I quartered the first feeding and added more each feeding , they are in a 10x5 tent there 2 450 watt lights one 400 watt and 2 100 watt lights they are all led two 12 inch oscillating fans at each end and the fresh air intake is 6 inch with carbon filter the exhaust is identical and the room the tent is in the windows are blacked out and it has a window AC unit always on pulling fresh air in the room and the exhaust is sent outside ,sorry I’m just trying to think of anything that you may need oh are in 3 gallon fabric pots they get fed 1 to 2 liters around every other day roughly sometimes every 2 days depending on how light the pot feels and thank you in advance for any help you can give me
