Drying out fan leaves/silver sheen or spots on l... any ideas?? seems to be spreading

This is troubling. I havent had a problem with leave on the plant looking worn out and drying up. Also, they have this shine that is white/clear/silver or something... i can figure it out, but it starts with the shine then the plant stops growing and then starts drying out from the bottom up. the single leaves were plucked from the base. the growth at the top seems to be okay, but they havent grown in 3 days...

please any ideas?

over nutes and maybe ph lockout
