If its not the damage from bugs that it looks like it is, does that stuff on the leaves wipe off ? I ask because I know some foliar sprays especially if its heavy doses will leave a residue on the leaves that looks very similar to bug damage.

Just breezed through the post and answers but you have bugs of some type. It's a "piercing sucking insect", no I did not just make this up, google it. Not a particular insect, but a general class of dozens of bastards. Thrips, leafminers, aphids, mites and more can all cause this type of damage. They pierce, and the suck, and THEY SUCK.

Always look on the bottom of the leaves, You will most often not see these little fuckers, whatever they are, on the top side when you have lights on. And buy a magnifying glass, even a cheap one, to confirm your suspicians. The insects can be, and usually are miniscule. Too small to be seen by my aging eyes anyway.

Peace
