Getting your first female(s) in the beginning is VERY exciting. I still get happy when I find out my lady is actually a lady.

It sounds like the stem maybe getting too tall and is having problems supporting itself, is that right? If so, you can put a small stick in the dirt, rest it up against the stem, and gently tie the stem to the stick, holding it up. That is your best bet because things are only going to get heavier. It is very common to tie plants up once they get too heavy, but so early in flowering, you need to resolve it.

Have any pics you'd like to share? If not, that's cool. Good luck!
