17 days flowering, need help!

Ok, so im 17 days into flowering, this plant was 4.5" tall when I went into flowering. NOW its 27" TALL!! and I'm out of vertical heigth in my grow box so should I "TOP" it or bend it over, and also the fan leaves have started to curl under (I fed it 1/6th Tiger Bloom then flushed when I saw the drooping and just re watered today with a VERY weak tiger bloom probly 1/12th)

the soil is FoxFarm OF in a #2 pot with 8 2700k cfls

i would think that your plant is probably done stretching, but if youwanted you could lst. but do it before it gets too far into flowering.

i dont think it is done growing
they close to triple their size in flowering

last time i checked my math 4.5 to 27 is more than five times? he's probably done.

ohh shit sorry man you are definately right
i thought he meant 4 and a half feet, but now i know it dont make sence haha my bad
+rep

Thanks for the quick replies, I'll try and LST it. Any suggestions on LST'ing? this is my 1st sucsessful grow and I don't want to F'it up

Also, the leaf curling is worring me if anyone has suggestions there

that leaf cupping is either overwatering or too high a humidity.

Humidity stays in the 30's

I tied the top of the plant over with a garbage bag tie last night (I onlt felt good about bending the top 5-6", hopefully this beast it done shooting up... I think its more sativa than i built my growspace for. and i'll give it 1 more day between waterings as it WAS around 1/2 gal every 3 days.

This is my 1st sucsessful grow so far.....IF I need to TOP it (only under necesarry conditions) would it screw my plant up too bad? I just want to get a moderate yeild and make my way through this 1st grow and I am getting a house soon and will have the proper grow setup with a dedicated room and MH lights and proper ventilation
