Do you have any of the hanging straps or tie downs? If you think it is having problems near the top, use a tie down and see what you can do. Also don’t worry a lot. I worry every time 
I open mine and think something is wrong and most times it is fine, just me,
That’s me too, you get me lol cool I’ll see what I can do in the mean time. I do have tie downs
I saw a few tiny brown tips on mine this morning and now I thinking it’s dying. 
I am all worried, but sure it will be fine.
Right lol but I know we have to wait the out come will be glorious hopefully lol
Mine was doing this the day after drain and fill the next day I topped off the unit and it evened out I think sometimes the nutrients on a new drain and fill can be too strong for the plant top off balances out the new nutes as she drinks 2 days after your drain and fill!
I can’t really give you any advice because you shouldn’t cut your plant at all but the light is getting to close, 
I guess let her keep growing and when she is touching the light clip the top leaves idk what else to think/say! You do some branch bending low stress training to her to slightly bend away from light!
Has it started to flower? I cannot see any white hairs
You need a scrog net/screen to bend the tall stems downward. They bend back up after a few days… this buys you time as they continue to grow toward the light. Next grow, do this sooner.
I did it once she Reached the 2nd fan.
It has not started no …
Yeah I try not too but some do get really burned and I am bending them as it grows like today more are back up
Get you some ties and gently bend where you can. If she don’t give don’t push her. Once you do it right you will know it. 
Lil update water change today got some to bend did clear some of the top. Some are thick colas just look at the main stem
Damn your stem is nuts like a Gah D**N oak tree growing!
LMAO, perfect picture you added little guy is using all his muscles 
Well no flowering yet I think we need a different alternative she is getting taller as we speak a lot more light burn what do you think of transferring to the tent any suggestions with that said what do I need to continue with the grow or what do you guys think
Out growing the Grobo is why I am debating using the Skunk #1 as I know that grows 1/1.5 meters and the Grobo is only 4 feet I think.
Didn’t think she will outgrow the box but she is and still no sign of flowering
