Hello All.
So your growning em, eu naturel? What time of year is it where you are? Do you get loads of lovely bright sunshine like I'm imagining? (stuffy bleeder:-) ) if so does that window screen block the light badly? I wouldn't expect em to stretch like that under a proper currant bun, (unlike the poxy excuse for a sun/summer we fuckin seem to get these days).
Unless there was a big queue of beasties, stood there lining up to scran fuck out of the plants, I'de get them out in the direct sun, that window stuff could be blocking out some of the valuable light.
Also you may be better going through a series of succesively larger pots, that could help with the stretching.
Do you know what breed they are, like are they a lanky tropical sativa or summat?
Also, unless your coming into your autumn, and your getting 12 hour nights they won't be showing any sighns of sex at all, so you could still have some females there.
But if you are already there and they are starting to flower you've really started a bit late. Maybe get em indoors under some lights, amd make sure you get some cuttings going ready for next year, a shade earlier.
Ta Ta.
