help with autos

hi ,got some free autos from attitude ,never considered them because i read potency was alot lower then most decent strains. I have afgan kush ryder from world of seeds and they claim over 20% thc content,65 day harvest over 2 z's,im gonna try it my question is can you top it to get some more colas going or are you supposed to just let it go ? Gonna keep it under 420 watts cfl 20 on 4 off.Thanks in advance.

Honestly just leave it IMO... I grew an auto berry Ryder and after harvest it wouldn't re veg. So what I'm saying is I think cutting it ended up killing it. Unless I don't know what I'm doin?! But try it out man. Good luck

thats what im thinkig, thanks

If you top it early, I think you would be ok. My auto went into flower fast though...faster than I planned. Turned out the bitch was hiding balls...she was atleast one z. Damn.
