Please help, something is happening to my girls in veg, they are 4 weeks only from seed growing in living soil with only airated tap water being added. Lights are 600w kind led\'s hung 4ft from canopy. Temps range between 19 and 25 with humanists at 60%. I am using pred mites and an ipm foliar of dr bronners and karanja oil. Seeds are karma genetics- headbanger, biker kush and old dirty biker. Thanks for any help!!
