oh.. I just ordered my first auto ones.. dont know anything about them..I was told STAY AWAY FROM AUTO, but im curious..LOL anyways.. have you thought of going with either a branchy structrud plant, and doing a little LST so it still has a low profile? i dont know your space requiremens or limits, or why you wish to go with autoflowering, but id look for either a fast flowering indica, and grow in a mini SOG style, same thing but like i said look for a litle bit branchier plant, then LST it, so u still have a low profile.. or if u have the space, go with a big pot, like a 12 or 15 gallon pot, plant 3 plants in it, and LST all 3 of them, youll end up with enough space for all three plants roots, and with LST them you can pretty much make your own canopy space for each one, this way youll have a pot that just has massive ammounts of tops coming out of it
To answer your question best as i can better though, as long as the plant is still growing NEW growth, then its still alive LOL so if you have small leaves starting, itys alive, after those leaves grow out, so long as you keep it healthy from now on, it should be ok.. it might be a trait to autoflower, hence me cautioning I know nothing about them, which is why i bought some.. i have an extra 200 watt cfl im gona use to do a auto grow just to see what its about
