Both plants are Chemdogging at day 51/52. Bottom feeding with 2 ml cal mag and 4 grams Megacrop per gal. The big plant has roots out of the little 6" pots they are in and the smaller one(which shows mostly yellow leaves) has no roots outside pots. They are in a clear tub and do have a tine bit of green alge but i clear it out regularly and it's got covers on the side to keep most light out. Do you think it's the slight alge or maybe she's not bottom feeding as well as the big plant and needs to be top fed some nutes?
