make sure you get GE daylight... 6500k spec, will work wonders for you...

as for nutes, that's pretty weak. i know there's lots of bad press on miracle gro, but i've use mg all purpose for garden vegetables 24-8-16 for years, with nothing but excellent results. start at quarter strength and work up. just make sure you get the all purpose that is for garden vegetables, as mg makes like 500 differen kinds...

for flower, use a super phosphate, i like green light products, especially superbloom.

you can use the karma with any nutes, as it is formulated to help metabolize nutes. also adding a tablespoon of sugar per gallon helps...

get some good nutes, feel it out, an soon you will have exploding growth

love, kp
