DWC system. Scrog. Using G.H Flora nutes. Lucas Formula. RO water
pH= 5.5. 900ppm. Room temp 68-78. Water temp 65. Humidity 15-30.
My plants have been vegging under 400w HPS for two weeks now. I shocked them during transplant but they have really taken off the last 3 days. You can see from the pics that the fan leaves are huge. I go in 4-5 times a day and try to move them so they don’t block the lower shoots.
I think I finally have things pretty much dialed in. But I would like some pruning advice for my scrog setup.
1. Should I remove/trim some of these fan leaves or just keep moving them?
2. Should I start trimming some of the lower branches so more energy goes to the top?
3. (for my next grow). I heard of a pruning technique where, You top under the 7th node, then remove the bottom three leaf pairs. Would this be good to do for a scrog setup? Or do I let them grow and keep bending them under the screen?
4. My humidity is pretty low. 15-30. Is this ok or would should I buy a humidifier to get it to 50-60?
Thanks for any input you can give me. Steve
