topping help

please help my plant is about 1 1/2 ft plant tall including pot and im growing in a 3 foot tall space is there still time to top or will it take too long for the 2 main colas to mature enough to produce a nice yield before they get too tall?

im probably on the 9th or 10th set of non-alternating nodes

if i supercrop will my plant still produce a main cola or when i bend it is it fucked?

i vote to try supercropping i just did it seems to work great and looks like you get alot of colas using that tech
