Possible nute lockout! +rep for help +PICS

kk, im thinkin this might be from a possible ph nute lockout, i think its been a bit since my ph has been around 5.8, its been in the 5.5-5.7 range... also, i sprayed my plants with a water/rubbing alcohol solution (had spider mites before) yesterday, and bleached the walls of my tent (though im pretty sure no bleach hit my plants). anyways, here the pics, please help, i will rep!

also, my ec was around 1.0 yesterday, now its down to about .9
ph 5.7
res temp: 65.5F
tent temp: 75
rh 55%

as i said my ec dropped pretty good overnight, maybe she just took in a little bit too much... getting prepared to up my ph with a bit of water...

growing in DWC, using dyngro grow, and protekt.

also, i guess i should note, the browning the in the first picture is old.

ive had plants burn after using too much alcohol in ant-mite concoctions , now i use it at 10% in water based mixtures mainly just to help disperse the miticidal oils when sprayed. it burns young plants especially under strong light

thank you, i spoke to a friend about this, and he said that could have done it. i did go heavy on that poor girl last night, and i think my mixture is 50/50...
