Indoor Flowering too early: fix?

[jingo]

It seems to me that my autos get big if slightly underfeed, yours look slightly overfeed. Do you get run off when you water? If not increasing your run off could help. In this stage of flower I usually am lighter on N and run about equal amounts of bloom to the N.

It takes time to pick up on things. Next grow less feed and pay close attention to your environment. If you are not running your lights 24-0 and your environment is not staying very stable than I would switch to 24-0 until you get things stabilized.

I haven't fed them for a whole week before they started flowering. And they showed signs of N def when I came home (first true leaves yellow). I'm not giving any Bloom nutes since I want them to grow.

My environnement is stable, as long as I'm home. Sun hits hard and temp might get too high if I don't open all windows completely during the day. They started flowering the only day i've been gone 24 hours in a row, do it might have been triggered by a heat stress. Otherwise it's very stable, 40-50% rh and 22-26C.

So it sounds like your medium was a bit hot to start and that head probably stunted them a bit. Never use that bio bizz myself some other Growers may have a soil just for starting the seeds they can recommend that's in your area.
