ok.

first, did u put your lights in 18/6 for vegging? if yes, well for flowering u should turn it to 12/12

second, 100w house light sucks. it wont grow your plant properly.doest have the right spectrum. u need high pressure sodium light or metal halide or bulb.(about 250 w for 4 plant is ok)

u need to use fertilizer after about 2 weeks of growing.

a fan would help em



ask more if u need

peace
