clumps of tiny white dots on my leaves

i have a clone of some supposed "church kush" from a friend of mine that has what seems to be huge clumps of tiny white dots mainly around the middle fingers of my fan leaves. my theory is that they are from the fungus gnats that infest some of my other plants as i believe the adults suck the sap from leaves. i was wondering if anybody with experience would be able to help? ill try to post pics ass soon as i can.

heres some pics i took wit my phone not the greatest quality...

spider mites? turn leaf downside up in bright light and look closely (w/ magnifier?)

get some pure spray green. it works better than anything out there and is cheaper too. very concentrate. $25 a quart. organic and omri listed. it kills adults, babies, and eggs. spray the underside of the leaves about 10 min before the lights got out and repeat 3 or 4 days later. it only takes 2 or 3 applications.

had them before n it doesnt really resemble the damage plus i didnt see any webbing.... but ill check just to make sure.

the webbing usuallly shows up after they been ther a little while it starts as yellowish spots on the leaves and then you can se em crwling around on the other side.

Azamax. That shit cures any infestation, which is what looks like you may be facing. If its spidermites keep your fingers crossed and pray. Those fuckers are ruthless. Good Luck

Also even after you kill em. take a wet cloth or wipe and wipe down the stalk and bottom of the leaves to get rid of the dead ones or even ones that got missed. and good luck. ive been there and know how frustrating it is.

Those pics are too blurry to tell for sure what it is. Have you seen the pests yet? Most all pests will always be found on the bottoms of the leaves. Spider mites leave little white dots, thrips leave silver looking spots, fungus gnats usually end up dying on top of buds, and aphids will leave sap spots on the tops of leaves. Get a 100x magnifier from radio shack for under $15 and look and any and every spot you see on bottoms of the leaves to see if you can determine what the pest is. Once you find out what pest you have you will know what product is best to combat the problem and how vigilant you need to be.

It's hard to tell from the pictures, so verify your problem before treating it. Your problem might not be mites or gnats at all...maybe it's something as simple as light burn from foliar spraying with the lights on.
