Could use some help

i was gone for a couple of days and when i got back home my plant grew more than i expected and my light burned some of the leaves, i'm not really sure what to do about it.

One good thing. Your plant grew more than you expected.

1 - how big is your grow space?
2 - cut the burned parts off

my grow space is plenty big now, but while i was out of town it outgrew the box i had it in. i cut the burned pieces off already, but will that cause it to grow differently?

it shouldn't, when you take clones off of it , it will cause new branch growth sites though
