so i'm growing a single plant in soil under 6 two foot grow tubes. it's on a 18/6 light schedule and i'm feeding about every three days. i'm moving the lights up every other day about an inch or so up. it smells so good already and is bushing well. but i'm freakin out about the whole male/female thing. she, well i hope it's a she, is healthy, deep green and doin well. i have seen pics and such to show the difrence between male and female, but when should i start to see signs and is there anything i can do to encourage female growth? oh yeah my baby is about 5 weeks old and about 16-18 inches tall.
