Need Help!!! 2nd grow same problem. Just transplanted 5 days ago. Plants were apprx. 4 inches. Everything was fine until 2 days ago. New leave on tops of plants are yellow with veins staying green. They are yellowing from the tips and outside edges in, but some are doing just the opposite. From the base of the leave to the tip. We have Fertilized twice with KLN, Grow, and Liquid Fish cutting the amount of fertilzer in half. Our first grow was a disaster from the yellowing. We lost everything. Yellowed all through veg and flowering stages. Could our water be a problem? We are on a community watering system that is feed by a creek that runs through the middle of a Redwood Forest. The water is not treated. Plus the creek runs across logging property. Might be too much information, but every little bit helps. (I hope) Any ideas? I have a picture I will try and add. Oh it's indoor and they are under 4 1000wt hps lights. Soil is oceanforest by Foxfarm. Out of 72 32-35 have started to do this. Please help!!!!!
