White crystals on vegging leaves

i was thinking my girls where kicking out some awesome THC but i have a young one in vegging that is showing tiny white crystals, like miniature salt crystals, on the leaves. i inspect plants under and over the leaves for any bug problems and there is not one bug. i use a soap based spray about every week also. I use a jewler's eye to see close. any ideas?

comparing the crystals to the ones in the budding tent, they have the same, these are NOT trichomes.

nice pictures man thanks
soap crystals, aphid shit, dried up nutrient salts, fungus....you should taste them to be sure.

Crystallized sugar if your sprays have sucrose in them. I get them after I spray Actinovate heavily.
