Get a PH meter and quit guessing about the PH is where I would start...if you're that broke, see if you can borrow one. Mine cost a whopping $10. If that's too much money, maybe try a pool test kit from someone you know, but you really should have some idea what the ph is...

Doh...just saw the date on this thread...probably too late now...

PLANT STRUGGLIN HELP so i have 3 plants in my closet under cfls. 2 clones 1 seed. ive been doing everything exactly the same to all of them but i woke up this morning to see one of my clones leafs turning yellow and brown and drooping. even the stem is turning a little brown. this plant does only have 1 cfl over it. my other clone has 2 cfls. is this because lack of light??
