Have lights on sunrise sunset. The been testing out best high intensity lighting schedule. Wish I had c02 to add into the tent. Plants were getting 1600-1800 par for 3 hours a day. I noticed they were getting slight tip burn so I lessened the light intensity a little bit and extended the peak sunlight from 4 to 6 hours. Now they get 1300-1400 par for 6 hours a day. They are getting really good air flow, humidity, temperature. I've been replacing the water every 2 days now and topping off almost every day. Just switched the ph from 5.8 to 6.5. I think that's recommended for flowering. Currently they get 2200EC I use ro water. They get 250ec of cal/mag. 400ec of lotus boost and 1400-1600ec lotus Bloom
