how long ???

well heres my problem in 5 weeks into flowering and the top half of my plant (california special) is probly 2 weeks till ready..but my problem is the lower half of the plant looks like the top did to weeks into flowering,because of no reflective walls.
my plan was to cut the plant in half and keep the light on the lower half of the plant untill its mature just wondering weather i have to wait like another 6-7 weeks or so till there ready?

they wont just die will they?

Yeh your gonna have to wait.Next time add side lighting.

You won't have to wait QUITE as long, but you're gonna have a nice little bit. Think of it this way, about the time you're done curing, you start drying!

I didnt even want the cupcakes, but I my milk/cookie ratio was off the hook

yer spewin aye

know of any fertilizers that are high in phosphuruss or watever and potassium

Honestly if you get any one-step that is for flower, and add superthrive @ the reccomended dosage, I'd say you would water prob'ly 2-3 times before you have to flush for harv. I use Botanicare ProBloom.

What do you want to buy for harvest?

i just wondering on how i can tell if my plant is mature enuff to pick i dont have a microscope anyadvice

Closest way is to look @ the color of the trichs. You can get close with the naked eye, close enough not to fuck it up too bad. Honestly, when the hairs look like what you are used to them looking when you smoke it (an almost brownish-reddish-orangish), then you are there
