Thanks for the help, I am using Bio Grow, Bio Bloom and Top Maxx. RO water is the supply source. I have been using these same ingredients including the water all along, with good results and healthy plants. Keep in mind that this is happening in both the flower and veg plants. RO filter need changed? Been about 4-5 mos. since I last changed it and I usually get about 9 mos. out of them. Thanks again for the help.
