Thanks for te Rep! I pulled the 2 tallest and 2 more of them over to a larger flower area. Cobs were too close to the tall ones, they were getting light stressed, I have a lot of light in that 4x4! I am going to UP the pH on one of the taller ones to see if it absorbs CALMAG more effectively, the cobs make plants more CALMAG hungry, especially the closer the plants are to the lights. The buds are getting bigger, but the leaves near the top of the tall plants are either really hungry because of the light intensity or just stressed out from the intensity. I am already feeding 10ml per gal if Magical, hopefully changing the pH will help. Will see in a few days! Will start feeding upped pH tomorrow on 2 of tbe 3BOG. I will share findings, normal pH for me is 5.9-6.1... I'm gonna up to 6.3. Only way to know if something will help or not is to try. If that doesn't help I will try upping my whole feed a little bit, maybe a little stronger feeding will help..instead of just upping CALMAG.
