When to switch to Flower?

First of all, in your photo, the leaves are yellowing during the vegetative stage - either the pH of the water is too high, or you're not adding enough nitrogen. Secondly, you can switch to flowering when there are 4 "levels" of leaves. If you did topping, you need to wait a week.

It's really up to you when to switch to flower. The amount of stretch really depends on the strain. You can use a couple different lighting options to help with it also.

Agree with Burmese, if yu switch now def a lower yield than if you wait a week or 2.. Train it a lil with lst for the week

double or triple sometimes!!!!! i would switch in 12 hour light right now!!! good luck with your grow mate!!!💪🙏

Hi there, As you are growing photoperiod you can stay on Vegetative stage as long as you want.Switching into flowering circle doesn’t depends on height of the plant if you have enough space for vertical and horizontal space.If you have more horizontal area, train your plant as best as you can.You can even perform HST by bending your main stem 90degree and promote lateral growth.Then give her more time to recover before switching to flowering circle.Fill the horizontal space as wide as you can until you think you got enough bud sites.If you change now, you might end up in lower yield.Happy Growing... ✌️

Seems like yu kno the answer. Yu can switch at 9" or 9' it doesn't matter . Just depends how much vertical height yu got to work with . Might even triple in size
