PLEASEE help is needed

first grow, flowering stage12/12, and the trouble begins... wilting, tips curling under, some tips turning slightly brown, smaller leaves are lighter in color, one or two older leaves are completely brown and dry... and i'm freaking out.. my babies

Need more info lights,temperature of grow area,soil,air(Fans) and most importantly nutrients being used and strength.

Wild guess: roots suffocating. cn

The drooping is usually a sign of over or under watering or the roots are hooped.

okay so more info,, and no judging on my amateur growing technique... lights are cfl, temp between 78 to 85 F, soil is 50% oldcastle potting soil 50% perlite, yes fan and air purifier, nutrients used during veg was schults and strength was 7 drops per qt.. and used one so far during flowering was miracle grow... i know i know.. bad idea. no judging

Schultz and Miracle-Gro can be used with excellent results. But you could be using too much. I still wonder about the roots. I'd pull and inspect. cn

i havnt used schults in like 3 weeks since ive started flowering and also only used miracle grow once so far and followed instructions according but while freaking out earlier i decided to just flush them.. so maybe im freaking out to much?

Need more info as TheSpiderMite said. You last pic tells a lot your light is insufficient your plants is stretching as the leaf size gets smaller. Major problem there because even if you optimize all other conditions you will not be able to successfully flower that plant with your existing light.

Flush the soil this looks like possibly a salt build up many growers on here scorn miracle grow due to hits high ratio but used properly can work magic.

Holy shit! your poor baby......

ive also noticed some stems on the lower branches are a bit red compared to the top branches... any other advice out there?
