SoG Gelato(fem) x Big Bud(pollen Donor)

Wind burn has been identified. I overlooked plants growing to close to oscilating fan I misjudged how much light was to much for my plants in the center of the tent. 2 tops were lightburned. I raised the lights. I need to switch from a lux reader to a Par reader. 3 plants are showing nutrient sensitivities. I will water those With lower PPM(300). The rest will get 900PPM Small black bugs are everywhere in the tent. I will continue to spray neem oil Watered 6Sep One plant is 36inc tall 1 plant hermied Day 2, the co2 solenoid balve isnt releasing co2. Switching to am open tent to allow fresh air in untill co2 can be fixed.
