Hey mate. You sent my friend Jondamon a post today with a Q, so i thought i would pop by your thread to see if i could answer your Q's...
Ok so.... If your plant is 3 feet tall as you say and it's been in flower for 2 weeks, firstly Get your light as close to the top as possible, The plant's will stretch like crazy when they search for light. But not too close to burn it. Also if hight is a problem then you could quite easily LST ( low stress training ) them so that they are not as tall and this will help increase yield... Do some research on youtube... Just type in LST and watch a few video's. you will soon see what i mean by this. its easy to do.....
I would say at this time, as I looked hard at your plant's they are not showing to be male or female. get a close up of any pre flowers you see and post them so we can have a better look.
Apart from that they look really healthy....
Research is the Key to making it happen. No research means problems...
Check my thread for good info.
