(First time grower)3 1/2 months and only 11 1/2 inches and Flowering?

unfortunately i'd have to say no. there are certain strains that would remain really small, i think lowryder does that, but slang is weed because it grows like one. a few quick questions...

1) how has it been fed over the course of its life?

2) what was the ground like where it was growing outside? (lots of clay? sand? etc..)

3) from seed or clone?

4) what is it in now? 100% soil? (did you mix any perlite, vermiculite, peat moss, etc..)

 

Are you sure those are HPS bulbs?

 

Probably not HPS lights if they didn't run you up $20 per bulb.
That might be part of the problem.
They might be HPS or HID but they don't seem like the right kind from those pics?
If there is no ballast or small box or something used to run those bulbs likely not hps.

Get some "CFL" from walmart $10 for two pack of GE 26w 100w equivalent make sure they say 2700k on them and set them up for 12/12.

 

Well,
you have proven those bulbs work! I will give you that!
Not bad to be honest with those bulbs man! Looks like you'll actually have some smoke. Nice work.

Couple CFL bulbs and a few hanging lamp sockets should beef your plant right up!

 

first off i would say definitely keep going with it... even if you only get a few grams from it, it's not a whole lot of work and smoking your own homegrown is very satisfying.

hmm well i guess the outdoor conditions wont change anything now, but for future, clay is not so great to plant on. outdoor roots grow deep and wide and they just can't really get through clay that well.

i'm not a fan of slow-release fertilizer but what's done is done.. unless you want to transplant that thing. if you just started flowering its got another 65+ days, but i've never transplanted in flowering before so i don't know how good it is for the plant, but hey, you dont have much to lose right? (no offense) do what the other guy said and get more/better lights. if you don't feel like spending the money, then keep what you have. if you think you'll be growing again, then definitely make sure you're set up properly in the light department.

in all honesty, given your plants growing conditions and history, and the fact that its already in flowering, i dont think it will grow a whole lot taller. probably some, but dont expect anything crazy. most of that vertical gain is in veg... i've heard plants will double in height during flowering, from a few different places, but my grow experience has never showed this. i usually top my plants tho so that would affect it again, get more light on it ASAP (if you plan on growing again in the future), the longer you wait the less growth you get!

re: 3-bladed leaves. nothing to be worried about, this is related to the maturity level of the plant. nutrition plays a role in the way leaves look, as do genetics.

 

the plant actually looks pretty good... its hard to tell tho with that camera and the tinge of light, does the plant have purple all thru it's leaves?? what kinda weather was it seeing before you brought it indoors..?

and if that is the only place on the plant that a leaf is twisted, then i would ignore it. probably got bent while you were working around it. if it starts happening a lot, then you have a nutrient problem.

 

hey dude who ever told you those bulbs were HPS was so full of sh*t its shocking lol

you mentioned twisted leafs, twisted new growth is a sign of PH issues, but i guess your not to bothered, as your not going 'all out' tryin to grow her
