Hellp?? yellow dead spots??autoflower??

Hey guys hows it going? i have two little girls going right now and im havin some issues.The first is a lil devilmatic autoflower about 4 to 5 weeks in(havent been keeping the best tabs) and the lower growths are turning yellow and wilting off?also the leaves are wilting down and shrivling.for some odd reason one leaf was wilted up but i think i corrected that by getting the fan off of it any suggestion would be helpfull.The other is just some bag seed about 2-3 weeks into flowering and the tips of the leavs are browning and there some dead tan spots in the middle of some of the leaves,also some slight wilting and purpleing of the stems.im just useing some mircle grow veg and bloom formulas in some green thumb dirt. ive mixed some banana peels and blueberries in the soil thinkin this would help as like an organic fertilizer kind of? idk lol opions on that?im new,but I'll try to get some higher quality pics up,Thanks in advance,

Your plant needs more light bro, your over watering it aswell. You might have nute lockout because your overwatering it, or the soil is staying way too dump. It probably needs some heat, looks cold and wet

The plant in the first picture is a male so you better kick that trouble maker out. Looks like a lack of nutrients. What kind of nutrients has you been giving. What what dos.

she needs food!!! give her 1/2 strength nutes(900-1500ppm) every other watering. and she needs light too, she stretched pretty far

the bigger ones deff not male my friend,lil'white hairs poppin out all over,but yes i deff over water'd the little auto flower. I started it a little later so i couldnt get the light as close,but its just the miricale grow veg and bloom formula's nothgin special.and ive just been putin a cap full in the water ,like a little bottle cap full but i think i might have tried to give the auto flower bloom nutes on accident. Plus im kind of leaning towards i gave the bag seed to much of the bloom to soon,i appreciate the advice and i will try to get maore accurate nute reading,and could u explain exactly what the ppm is? i know it has something to do with how well the plant can absorb the nutes? Thanks again guys

ppm is parts per million, the more fertilizer = higher the ppm, but i just post that ppm thing for people who want it. but like i said use1/2 strength every other watering. i have lots of experience in using different commercial brands, and the key to using them right is to; only use half strength every other watering, that's the sweet spot. especially when using miracle grow.
