White on lower leaves. Possible parasite or something?

[RemeberMe]

The white part will quickly take over a leaf. Seems to only hit the lower leaves that are not getting full light (not seen on top leaves). This problem has affected some of my older, flowering plants as well that have not gotten dirt on them or ever been folar fed. Any ideas?

Looks alot like spidermite damage, only worse.lol IDK, maybe it is spidermites, I've just never seen damage that bad. Flip one of those leaves over, and you'll see tiny bugs crawling around, if you have mites. Hopefully you don't, 'cause they're a bitch to get rid of.


Have you sprayed your plants with anything?

I looked under a bunch of problem leaves but nothing was there. Just a few days ago I tried a weak bleach spray. I'll see if that helps.

Hmm...mysterious white spots, and no mites? I'd say it's the bleach spray that did it, most likely.lol

I sprayed it AFTER I got the white spots.

Looks like it might be powdery mildew, or some other sort of fungal infection. Drench it with neem oil or some product that contains neem oil, it can cure a myriad of problems.

IDK man, that's a tough one. Scroll down to the section on thrips, and check out the two pics. http://www.icmag.com/ic/showthread.php?t=11688 They look like possible suspects.

Yeah, neem oil works for mites too. I keep some around because it takes care of many plant parasites.
