When to start flowering ???

top it. it will get bushy. or LST.

flower it when the stem is as big as your middle finger, and a strong root ball is formed. that's me. i don't know what your goals are.

I'm using plagron royally mix an the stem isn't that thick but it's small and compact would I not b able to flower it now? Il put pics on later

you can flower it now. depends on what you're doin.' what your grow plan is. i just find that big buds grow on sturdy plants. why not top it, and veg a little longer? bag more gear maybe.....

I'm to impatient haha, do you think I should add a bit nutes even when using the royalty mix?

if Royalty is a "hot" soil, i would say, no. do not feed. if you are going to flower now, wait until you are in flower to feed. and not too much.

Thanks man a lot of good info
