Just Super cropped my critical plus......./ White Widow tops curling

So yesterday i decided to top 3 of my plants which are about 4 weeks old looking very good strong and healthy, running 600w hps with ff soil and ff nutes. My question is how long will it take to heal and form a knuckle where i broke it? Also there are some very small tears in the plant where i bent it at as well is this ok ive seen mixed reviews the sprouts are all facing up 5 of em that were on the bottom looking real good, just worried about the actual bend point is there a point where its to far and the plant wont recover? id say its about 75% bent and 25% sort of a small rip and tear no longer then an 8th of an inch any ideas will try and get pic. Here is a few pics of an udate of my plants hate the hps lights gotta catch em right when they come on got like 3 minutes of no lines......

any ideas of y plant leaves on only white widow are curling up minumul only at top tried to show where

so 100 views someone has to have an idea......

way too hot, curling up is there only way of letting you know. Takes about 1 week for the nuckle to form, another 5 days before trying to move that branch is very tough to do.

regards,

Its hard to say, i cant really say from the pic.. For some reassurance just prop it up with a stick.. Or a peice of wood.. Just to give it some support, so it can heal itself quicker
