What to do with this?

Plant is 2feet 6inches tall and its all ready tuching my t5 light to the point its turning the the leaves a orange color and my tent is only 5 feet but the pot is 8inches

so 8inches+2feet 6 inches i cant raise the light anymore i just gave it its last raise and its less then 1 week into flower i didnt know t5s were so strong to the point it makes the leaves turn color its a nasty orange color but besides that its going stong
what im asking is whats this bending i hear to stop the growth?Can i bend the top bud site?can i cut the top?

Its low stress training where you gradually tie and lower the main branch until you get a horizontal plane it along the length....
Google lst or low stress training and theres some good guides and videos

i seen the videos i know what to do -_- what im asking is can i do it to the middle root? the one thats from the dirt to top?

ouch, well, at least youve learned for next time. Bending it will help with the height, but it wont stop it growing, so i hope you got plenty of horizontal space. you may need to be a bit rough and have to sort of weaken the stem squeezing it with you fingers so it bends and doesnt just snap. for the future count on your plants to double to triple in size from when you start the stretch phase of flowering to when its done with the stretch phase.

it grew for 2 mounths in veg i didnt belive that it would grow this fast since my first fail grow was a duded and it just got bushy wheni turned to flower it was all ready 2 feet

in a week since i started on the 26th of feb it has grown 6inches

so i have a week intoflower got what more then 55+days left man.

on a quick note it has all ready started bending on its own from lack of space its cruving to the side if i starigten it it becomes 2feet 10inches sigh

just bend it right over if you have to. Once it gets buds on it, you will be propping it up.

Like someone said before, pinch the stem hard and fold it over. It is called "super cropping" if you wanna look it up. Bruise the shit out of the area, the more the less likely it will all out snap. In the end though, it will probably split, but its fine, in 2 weeks, it will be almost fully healed, and be like 10 time stronger. If you just bend it a bit, it will go straight back into the light. You gotta believe, its a scary thing to do the fist time, but now I do it like 4 weeks into flower (for a 12 week strain) maybe even a bit longer. It is amazing and you will never go back.
