Autos begin to flower anytime from about 3 weeks to 7 weeks, usually around 4-5 weeks. Hot/cold and hours of sunlight don't really have much of an effect, other than you'll get more growth with extended sunight hours. There's not a lot you can do to extend or delay flowering. They flower when they flower. Photos are much more forgiving of mistakes/isues because you control when they flower.

Thanks for the heads up. So should I now be feeding with nitrogen rich feed or potassium rich feed? What them to grow but at the same time if they are starting to flower, I'll need promote that growth too. I am dissapointed that vegetative growth seems to have stopped..

Hello hive mind! I hope you can help!
2 plants, Northern Lights autoflower (started lst see photo) and F1 Hyperion Autoflower. Both potted in fabric 20l pots with westland young plant mix
NL has started flowering prematurely and have nonidea why! Recent hot spells, but notnleft to dry out, fed with biobiz grow, in a greenhouse. Not doing things scientifically and have never grown before but I assumed autoflowers where on a genetic timer of sorts... really didn't expect to see flowering after 7 weeks.
F1 is a couple of weeks behind the NL but also showing signs of early flowering.
greenhouse day time temps kept between 30 and 20. Night times temps down to typical zone 9 no extra heating provided.

So 20l fabrics with seedling mix? Cant find this specific mix from Westland you mentioned but i'm pretty sure that it's a factor in the stunting. You also mentioned nutes. At what time did you start using those?

I've grown a fair bit of autos by now and flowers in week 7 are normal, they should be pretty prominant actually since an auto can take about 60 to 90 days to finish. True premature flower happens way sooner in the process.

What likely happened is the plant stunted during veg due to some problems in the soil, lighting, ambient temp or a mix. Especially if they've been outside since april/may? Regardless of a greenhouse unless you run lamps inside. If for instance the rootzone gets too cold, they will grow really slow (around 15C and below is when they practically stop)
With added LST to recover from it can really stunt an auto. They will flower as usual but wont get to the size they should be, including buds.

Keep trying, next grow will always be bette
