p.s the leaves are wet because I sprikled them a bit.
I heard flashing the leaves with just water is good for them.

well yea If you guys can tell me what the problem is I would be VERY greatfull.
the temps in the cabb dont cross 85 H's and 59 L's average temp durring the day is about 75F

Thanks alot guys

Where's the rest of the plant??? LOL (just kidding sorta)
Just doesn't look like enough fan leaves to fuel the buds IMOHO.

Temp swing is too much. 15F swing is max (book smart comment)
The High is too high.
And the low is too low.
I doubt the average H temp. Yeah mathematically it works, but if the 75F happens/reached at 1.5 hour into lights on and continues its upwards trend, its a skewed statistic.

How long you in 12/12? Buds look kinda nice and yummy! The plant will twiddle off as it reaches maturity.

they have been in 12/12 since the 4th of october. and I know its not enough plant because I flowered kinda early. its ok thou theres a few 3 footers waiting to be flowered
