help plant problems,

Ok, so i have six 24watt cfl's, a fan for intake, and one for exhaust.
the lights are about 1-2 inches from the tops,

anyway on the fan leaves, i keep seeing these spots and its starting to take over the leaves,
i water everyday, unless it looks over watered, i use miracle-grow all purpose plant food (24-8-16)
and right now i have this one plant into flowering,
been in flowering for about 2 weeks, already showed sex (female)




all these are from the same plant.
there is some info about my grow.

any idea's what the problem could be?
i checked the faq but it didnt help me

Looks like nutrient burn, how often are you feeding? You shouldn't need to water every day either, let it mostly dry out and then pretty much saturate it. I'd also add some more CFLs or an HID they pay off come harvest.

Edit: Oh, and just give it plain pH adjusted water for two weeks before feeding it, and mix the nutes at 1/4 or 1/2 strength.

you should not be watering everyday... water more quanity with far less frequency.... stop fertilizing your plants for a couple waterings....

are you pH ing your water?
