What bug causes this??

I posted this pick the other day thinking it was thrips, but no. I purchsed a good mag glass and had a look. There is a bunch of tiny white bugs, less than 1/2 cm that you can't see with the naked eye. I have sprayed azamax, azatrol and spinosad in the past to slow this damage down but it's not working. A lot of the bugs (on top and under leaf) look dead but some are moving for sure. I don't have a way to take a closer photo.

My opinions is it doesn't look like a bug issue. I understand you have them, but the second pic looks like, because of the leaf curling (and dark green coloring), over-fertilization. How about a pic of the buggers?

Can't see the insects but if you say they are there go get some biodegradeable mite spray/solution (mix it with water (and Hydrogen peroxide)).

The contort, wrinkling & curling of the leaves (if you are certain you haven't overfed) could be zinc deficiency.

Maybe spider mites or white flies?

SSHC- I was thinking the same for a while, I'm using organic soil that I amend with either worm castings or sea kelp extract once a week. I thought it may have been nutrient lock up and just the other day gave them a drench with 1tsp epson salts per gal. Think this may be helping a bit.
Sorry I don't have a camera to take that good of a pic.

This is the best I can do as far as photos go for now, they are tiny and hard to see, both sides of the leaf.

Get a incesticed like K0ijn suggested and go to town on them.

damn its root aphids for sure, look in your soil there are tiny speck white jumping fuckers. they suck the life out of the roots. drenched my plants the other day havent seen one since but the decline of the overall health of the plant is excelling as the new white hairs are now turning brown again. i dont know what i am going to do. maybe chopping to make wax is the only logical thing to do.

by the way how is the epsom salt bath working? when did you do it?

Swissbraid, This problem sucks. The salt bath was not as effective as we hoped it would be.
Sounds like you have the same prob as us.
Here is what we have narrowed it down to, Fusarium. It attacks your roots and makes your plants weak at the base. I'm sure people on here know more about it than me.
I'm going to try some "Insect Frass" manly because that's what I can get my hands on now. Have heard that this can work good.http://www.organic-gardening-shop.com/agorganics/Product_Details.aspx?ProductID=113
