I took these girls(clone) over from another caregiver and was told they are sensitive to light. During the veg time under a couple CFLs a 400 watt MH and a secondary 100 MH for side lighting everything went like gang busters. ( i disregarded the warning)
SO when it came time for flowers I set them up with two 400s (one MH and one HPS) at about 16 away. Again everything went good, so 4-5 days into it I lowered the lights down to about 10 with the hood making a ^ shape over the plants (less plants than light spread) in a space no bigger than two hoods, I would say 3x2.5. Well the flowers really started blowing up [genious right?
] but after a week or so the plants started turning yellow/white uniformly on all leaves.
After doing some math 3*2.5=7.5 800 (watts) / 7.5 = 100 watts per sq foot..
WALA! Light bleaching..
I raised the lights up a little, and started opening the door during light on cycles
to get some more frsh air and things started looking a little better with any new leaves (on the flowers). and the this laps
