@theoracle,
Do u think that the N is locking out P and other nutrient? 'Cause I wasn't feeding them before they showed deficiency symptoms, and I always keep the feed like at a fraction of recommended dose (Grow less than 1/4, bloom less than 1/2). I checked the runoff ph and looks in range for soil, so at least that's not the problem XD and also they never looked dark green like my previous overfertilized plant ?_? And the burned tips showed up on lower canopy before the firts fertirrigation :o
