Major Problem With Outdoor Blueberry Grow

I have a few outdoor blueberry plants that originated from Northern California and are medicinal grade plants that are currently in their 3rd or 4th week of flowering. This is my first grow ever and I have been searching the threads for about two weeks now looking for this very problem but have not been able to find any solution... the problem is that all over my plants, there are very tiny yellowish brown spots (about the size of the tip of a pencil or pen) all over the fan leaves. I am wondering if these are spider mites? Although I was told that these should die off of the clones after being planted outdoors due to the harsh outdoor conditions. My plants now are very beautiful and tall sativas that average about 5 feet in height. I will post some pictures soon if needed, however I am looking for some feedback from experienced growers as this is my first grow and first problem with my grow that I havent been able to find a solution already listed on this site.....sorry for such a long post,... any help would be much appreciated.

spider mites arent yellow, they are black and they eat your leaf. are the yellow things bugs or a fungus? do they move? is it killing the plant or is it just there?

It isnt killing the plants, the spots are just all over them, and a 52 year old guy that I got them from said that they should be just fine as long as they are green ha but i was just checking for other peoples opinions, I will have some pictures soon to explain myself a little bit better

the major problem is they gone
