whats up with these crusty leaves?

my leaves are shriveling and changing colors and getting like huge white spots and tears. ive looked for bugs with magnifying glass, didnt see anything thought. maybe a problem with nutes? i just put to 12/12 a few days ago. please look at pics and give me some ideas. im running a dwc hydro system with botanicare pbp line. i was also on stinkbuds nute recipe. switching to use bloom today.

Pic 4 looks like what happens to some of my leaves that are too close to a fan.

Not sure about the others though. Is it all over the plant?

looks like bug damage, have you looked at the underside of a midleaf with a mag.glass?

Magnesium deficiency.

yeah the fan is somewhat close. the plant is in the middle of the room and the fan at the edge, but ill try to move it as far back as i can. it is still on pretty low setting. its just a normal room fan that oscilates and has 3 speeds. but the bad leaves are really only under the top, but there are a few leaves on the top level that seem to be turning out crispier too, but not shriveled like that one.

ive searched everywhere. i mean i turn it over almost hoping to find something but i never do. i know thats a good thing cause bugs suck haha but im sorta confused whats going on

pic 2 and 3 is definitely magnesium deficiency. try adding just epsom salts(1 tsp/gallon)


having an excess of calcium will induce a magnesium deficiency which will show up as a chlorotic condition on the lower leaves

I would almost never recommend upping CalMag unless you are ABSOLUTELY sure that is your problem. It is super easy to burn the shit out of your babies with that stuff (speaking from experience.) I would go ahead with the flush and go from there.
