help it will not stop growing.

My lemon amnesia plant will not stop growing it was only meant to grow to 70-80cms and now is 140cm. i am doing 13 hours dark and 11 light but it will not start flowing... what am i doing wrong?

cheers in advance

go to 12/12 and hit it with some bushmaster

Do some LST, plants just stretch when they go into flower. Did you top it?

I started with 12 12 for a week and a bit and not much happened.
Lst?
i haven't topped it. should i? how exactly do i?
what is bushmaster.

sorry for general stupidness. i have done a fair bit of reading up but there are so many conflicting ideas i am finding it hard to make sence of it all.

cheers

topping is when you cut the top off. that way it grows 2 top branches

bush master is an additive that keeps them from stretching when you flower

LST low stress training. tie your plant down so it grows out not up

and plants stretch the first couple to few weeks of flower then stop
