You tell me what the problem is...

I can't figure out why the leaves are curling up/down and some of the leaves are super dark green and I'm pretty sure I haven't been over feeding... not 100% sure

what kind of light?

IT's flowering now under CLF's

i noitce this on my plants as well-not all leaves but some of the new leaves twist downwards....donno go no idea from what could it be... m growing under sum light

Flowering under CFLS

I'm going with overwatering, but it doesn't seem that bad yet if that is what it is.

Yeah i say same thing Overwatering, rule thumb yu cant water too much but too often so when yu water, water it good and let then dry well, very well but not too much!
it looks good, but it might look more worst if yu keep overwatering. there maybe might be heat or temp prob's too, but not so bad because plant looks fine no yellow....
dark color mean your soil is over 5.5ph like something 6-8, if your plant looks bright green, little yellow then your ph is low like acid. hope this helps!

yup theres the problem

im getting a cool cab tommorrow so i'll hav3e HPS

So I got an electric soil tester today and it tested at 7.0 so i got some lime and applied it to the soil hopefully that will lower the ph and i figured that since it is too high the fertilizer was building up and couldn't get to the roots very well hence the curling ofthe leaves so i think i figured it out.... THNKX for you all the help guys...!

in other words the wrong portions of fertilizer were getting in so there was too much of N or P or K

i thing yu should flush everyweek or every another week your plant roots and hole plant, it make ypur ph staying better and it will do good for your plant !
