Ok heres the deal, i grow using a 400 watt hps/mh light system in a 3 foot by 6 foot closet, with a 8 inch 590 cfm inline fan mounted 12 inches from the air coolable reflector hood and vented into the attic. I have 1 lowryder #2 three-four weeks from harvest under a led grow light. i have 5 himalaya golds, 1 purple lady, one pure power, one pure gold all in early veg stage (2 weeks veging). all my plants are lush green and growing fast. but!!! the very end of the leaf tip is steeply bent own and the very extreme end like the last 1/100 of the leaf a very tiny spot is yellow and eventually drys and crumbles, but never really gets any worse and is not inhibiting growth, it has happened tp both the lowryder #2 in full flower and the other 8 in early veg. i use a foxfarm nutrient program with some bontancare products mixed in. also superthrive. I AM USING TAP WATER. i grew two plants before these that this did not happen to. i used distiilled water i bought them in gallon jugs. im not sure what exactly is going on, and does anyboy know how to solve it, besides a water filter. any advice is helpful.
