Plant problem (droopy and yellow/brown leaf spots)

I'm not sure what the problem is. I water about every 3 days or when the dirt is dry, the light is a 48" flourescent full spectrum and i keep it close to the plants, i did use a 15-30-15 nuts when i started the flowering about a week ago and then noticed the leaves starting to droop and crinkle and get crispy (yellow/brown color). I have nuts i used before that was 10-15-10 and had no problem. Any ideas what it would be? this is my first grow so I'm a little new with it.

you could have to much p&k in there the plants look like they are still in veg so you really need to change to something with higher Nitrogen like a 10-0-0 to 25-5-8(what i use for veg.) the 15-30-15 stuff is for flowering.

They are supposed to be about a week and a half into flowering because I've been doing the 12/12 hours of light and no light gets in when it's dark. So is something wrong with them since you say they look like they are still in vegetation? i haven't been able to see any sacs or pistols either...

Why do you say they are still in vegetation if my hours are 12/12?

because your plants don't go into flowering phase until they've started flowering or have shown preflowers. Just because you switch to 12-12 doesn't mean your babies are automatically flowering, it just means you've put them into a flowering light schedule for sativa's/indica's. If your plant is mature enough it can flower within a few days of 12-12, or it can take a few weeks to show sex and start flowering.

I've been able to see the sex of them now. One turned out to be a male or atleast looked like it had balls (first time so yeah) and the other has white pistils. I cut down the male so all is left is the one female.
