Should I top this "auto"?
I planted this monster thinking it was an OG Kush auto, it's been 8 weeks and there is no sign of flowers, got almost 2 months until photos will start to flower, and I'm scared this thing is going to be 12 feet high. There are 2 kush xl autos behind it that are the same age, and are well into flowering.
What you think I should do?
It's too big for lst, should I do a big top, and try to clone the main cola or what?
Cheers guys.
Edit- Just to clear a few things up. I don't think this plant is an auto. I got it as a free seed from a head shop, it was labeled as "kush og auto". My other kush are indica heavy, she is clearly sativa, and is over a month late in flowering. Clearly a photoperiod plant that has been mis labelled. I wanted other people's opinions on whether she is an auto or not, and what is best to do if she isn't, as I have let her go for 2 months without any LST, or topping. Sorry for not being clear originally.
