What is this? Broad mites?

My ph is 6.9 to 7 and she's a gorilla glue. I plucked 2 off that were tacoing . the one in the bucket is a sour diesel. Both are clones . The rest of my plants don't have this going on yet. If so it's very minor but the upper leaves that I'm hesitant to pluck because there the only big solar panels these lil ladies have yet. The last it's a picture of my ak47 clone and she doesn't appear to be affected by whatEver it is.

this is one of the autos and it's started to do the same. I'm. hoping it's something correctable as I've added a table spoon of Epsom saltper gallon the last two times I've watered and some vinegarto lower the P.h. . Any advice would help
