hey everyone!!!! bads news and i dont think its normal.....

my clones leaves are yellowing and starting to shrivel (no pics, im at work)
I CUT THESE ON 8.27.06
here are the conditions: closet space 2'wide x 2'long x 6ft. tall
my temp ranges 79'F-86'F and humidity is around 34%-41%
i have a fan on top of the grow box blowing in at 55-135 cfm. (depending on fan speed)

and im misting them about 3-5 times daily and keeping the potting soil damp, i have a 1 dome for 2 clones that i switch between the clones every 6-12 hrs. (the dome has 1 1.5 inch hole in it)

why are these things yellowing and shriviling????? but the stems still green and so are 2small leaves

is it humidity (what %should i be at)

by the way lighting is 6 48" floro tubes (2 of 6 are grow tubes) and 1 13watt cfl over the clones


WHAT TO DO
!!!!!
