crizzo- those are some healthy plants you have there. The only one I think is a female, from what I can see, is the one in the 2nd picture. I think I see a pistil. But I could be wrong here- the pictures aren't real clear. How long have they been in flower? If you see two little white hairs protruding from the calyx than you have a lady. You probably already knew this.
And I know what you mean about the AI stretching. I have a couple in flower right now. The one I put in first didn't stretch too bad because it had the light to itself for awhile, but the other AI I put in next stretched like crazy. I mean going from 14" to like 35" plus, but it was my fault because she wasn't getting enough light. But they do stop eventually :laugh: and from the sound of it yours may be done. Oh and they grow colas that are an additional foot- so be prepared for that!
