Was told to post this here, big problem

Been having an issue with my plant, was told to post my problem here because i was not getting many responses under my grow. For basic info concerning the grow, here is the link

https://www.rollitup.org/cfl-growing/278068-newbie-questions-his-setup.html

I will re-post the pics here for all of those who do not have time to review. Maybe a diagnosis may be suggested. I'm thinking overwatering, i've now not watered in 3 days, the top of the soil is dry as dirt, waiting for a response as to whether or not i should water soon, for i don't want to lose her. Had 5 in the begining, she's my only female.

Thanks to all who respond, and any input on the original thread would also be appreciated.

First 7 pics in the order are of the problem, the last 2 are pictures of the top bud.

What kind of soil?
What kind of light?
What kind of nutrients? How often?

Seems like it might have a nute problem to me.

flush it good and give it no nutes for a few weeks until it perks back up.

Looks like under watering to me except for the spots?

did ya spill something on them or spray/mist em?

never. It started as one small spot on one leaf, and gradually over the last week, the one spot got bigger, followed by more spots on the same leaf, then as those got bigger, it started on another leaf.

Light is a combination of CFL's. Total of about 240w of ACTUAL wattage, LUX (lumens/sq. meter) of 82,000. It's a grow space of about 1.53 sq ft, and i have 2x42w 2700k 2700 lumen cfl, 3x26w 5000k 1200 lumen cfl, 1x23w 6500k 1150 lumen cfl, 1x14w 2700k 550 lumen cfl (that one may be off on the lumens), and 2x23w 2700k 1100 lumen cfl. It's in a kinda confined space, but while the lights are on, i have a small tower fan on the inside blowing directly on the lights and plants, and then outside another fan blowing in to circulate the heat generated out of it, because early on, heat became a problem, and i was, at some points, reaching 90 degrees F.

Not sure of the current temp inside, haven't checked it in a while since i've been blowing the fans on them, but i have at least doubled the light since then. Could heat cause these symptoms?

Soil is the crumbled up peat pellets that i started the seeds in, there were 12, and regular potting soil.
The nutes, i started with a miracle gro tomato fertilizer, think it was 24-8-16. Then when in flowering, i transplanted and put some epsom plus into the soil (0-0-22). Then over next 2 weeks fed twice, once with 3-5-7 mixed with the epsom plus. then next week with 15-30-15 mixed with epsom plus, both only half concentration, to bring it to 7.5-30-29.5.

I thought over-nute too, already decided not going to use anymore.
Don't think it's under watering, the soil is dry as hell right now, i'm thinking about giving it a small amount just in case its dying of thirst, and just seeing how it goes over the next day or so. Any other suggestions or comments on this?

Oh, and i'm new at this, never grown anything indoors. How would i flush it? Is that just watering it constantly and letting it drain out the bottom? This isn't a hydro set up where i can just readily dispose of any liquid, it'll get soaked into the soil. Sorry if i sound ignorant, i just don't know.... That's why i'm here and why i'm a newbie, ha...

Maybe I'm dumb and someone correct me but that seems like a lot of light for such a small area, maybe too much light? I know riddleme would know about that. And they seem like nute burns.. so flushing would work. And to flush. Its basically a gallon of water for each gallon the pot size is.. So yeah just keep dumping the water in and let it seep out the bottom. And for the water coming out the bottom.. Idk how big your pot is but get a bowl or something.. maybe stick it in the bathtub for a little bit to get most of the water out

I would say over watering for sure. I've let a plant go two weeks without water and it did fine, so dont worry about that just ease off see if it recovers. If it doesnt, and I expect it will, flush by slowly dunking your plant in a bath with clean water and then lifting it out, letting all the water drain out, repeat 3 or 4 times. Also never use Miracle grow, it sucks for weed. and you don't need all that light your givving it, ro save a bit of electricity and lower the temp a bit take a few out.
