Please take a look at the 3pics named PROBLEM in the gallery, leaves seem odd...feed Ph-ok EC-ok, temperature/ humidity ok other plants are normal ex. Crystal Meth- exactly same program- looks ok...can it be that she is underwatered? wind burn? light to intense? out of clues...
Try to cut down that cal -mag I remember my last grow leafs were like that curled on top.. somebody here told me to cut cal - mag to half and it worked. Hope it will workout for you, looking good thou!
Hi @Guerrilla! She looked underwatered, but if your EC was really 3.6 then it's probably a nutrient toxicity. I'm glad to see she's much better now, take it easy with nutrients, autos are very sensitive. Happy growing 👊
