Seeking for advices,is this plant flowering too soon?

[fo88hrabrim]

This is my first time planting and my original plan was to transplant the seedlings outside,but people here at forum told me they are too stretched and it ain't good idea cause they will probably die as they lack in strength,it is probably good to mention that this plants were seedlings for 3 weeks growing ultra slow cause they didn't had enough light,so i've built a improvised box and gave them three 38w CFL lamps and three plants survived and are now growing,and one of em is quite big and they are now about 40 days old
Now what is troubling me as a rookie in this sport is why is this big one already showing pelts on top
they are on 24h light for 16 days now and i gave em no nutes yet,only occasional small amount of milk and neem oil
this plants are either Jack Herer,Cheeze,White Widow,or Amnezia haze
all i know when i bought em I took 2 feminized packs and 2 autoflower packs
could it be that this is autoflower so it is flowering already?

They need nutes by now. You have starved this plant in too small a container as well it looks. Doesn't look like theres enough room for plant to get much bigger, let alone produce a nice cola. You have to transplant it to a larger container with fresh soil. First flush it (100% runoff), then wait a day or two (keep in veg). Now water at 1/4 strength bloom nutes with low nitrogen ph adjusted to 6.3. Then fresh water next watering, then 1/2 strength. After that 12/12 lights. However, really I would say just start over. This plant is not going to make much for you, not worth the effort.

I've grown plants in smaller containers.

Yeah dude I've seen plants grow in smaller pots too,and as I have mentioned in above I will transplant it outside anyway
and why then would it be not worth an effort if its going to be outside on 12h direct sunlight everyday,will it not grow and bud by some logic?
