IR,

My flo tubes are high output and are around 1200 lumens each.So I get the 2000 lumens/sq ft that I saw recommnded somewhere on the net. I will try to fit in a single tube warm white tube when flowering.
Did my best to study over the grow guides on the net before planting.
Except for these yellowing leaves the plants are ok. Very good stem size and compact. Growing about 1/2 '' per day.
Only looking to get a few ounces out of 3 plants.
