Brown leaves with black dots

Hey everybody, question about a few of my leaves disentegrating - they have basically been turning brown with black dots, and also, quarter inch catipillars on the leaves as well - I blow them off, but they do have a tendency to return. Without pictures, are these spider mites? Also, it's starting to flower, and I don't really want to spray a lot of stuff on them - in the GrowFAQ it has a recipe for a deterrant, but is this effective in my stage? If not, are there alternatives? Thank you for the responses!

Hi Wutang..

No it is not spider mites.... is it juyst the lower leaves that are turnig brown

Have you tried "no pest strips"...

these are NOT the sticky yellow strips...

It's not at the bottom, more towards the middle - and I have not seen these - can I find them at Lowe's, or a garden shop?

Dude I think I'm having a similar issue with one of mine. Two of the main leaves are still really green, but are developing a weird yellow-brown patch on them with tiny black. Insect free for me though so I'm not sure wtf it's from. Started before I transplanted it, which kind of shocked it a little but now it looks like it's recovering but those brownish patches are getting bigger...wtf?

picture please.. if this is only one leaf, it is no big deal....

did you say 1/4 inch CATERPILLARS?

Haha, I believe I did - I guess inchworms would be a more accurate description? I'm no entomologist, but one of my leaves has about 8 quarter inch worms that are "sea green" in color. Other then that I don't know what the hell they are.
