Sounds like you have them in too big of pots...did you not transplant??? I start mine in solo cups till it outgrows them, then into a 1 gal pot, then a 3 gal pot, and finally into a 5 gal pot...they grow better that way..IMO..good luck and welcome to RIU

Dude no auto flower is getting 6ft lol. Most finish at 1-2 ft tops. Id say they are a bit stunted and as a result they are miniature. Dont grow auto flowers, they are finicky and once mistake and you get 4 inch plants. Just grow out a normal strain and it takes the same time and you get better yield potency and resilience.

i had them in 1 liter pots an then transplanted them straight to 10 liter pots do you think this could be the problem i know that when it starts flowering its gonna maybe double but do you think i will get quite alot of yield cos it has a BIG chunky stalk thanks for the replies

I'm going to say no on a big yield. 25% of clipped wet weight is what you will end up with.

even the one thats not an auto av not started to flower it yet i was gonna wait until its about a ft high or do you think there is no point

No absolutely the more veg you can get out of her the better off you will be. The bigger she is, the bigger your bud sites will be.

so you think maybe wait till she gets a foot high an then flower

I would guess you have your lights too close. Actually 600 watts in a space that size sound like the leaves don't feel like getting up in the morning so they just stay in bed. I would try raising the light for a few days.
