Plant problems

I have some pink kush clones in my 5x5 and recently they started showing some weird spots that I haven’t seen before. I’m hoping somebody can look at these pictures and give me some ideas.
I always use sensi grow and sensi bloom. I keep my tent around 22 degrees with 60% humidity although recently they have been going up higher during the day time cause of a heat wave in my area. I use a Mars TS3000 light. I just switched my lights from 18-6 to 12-12 5 days ago and at the same time I gave them sensi bloom. Yesterday I gave them regular water. Pink kush is usually an easy strain for me but now I have this problem that seems to be affecting every plant in the tent. I’m panicking somebody help me!!!

Looks like spider mites with all them spots on the leaves. Check under the leaves with a loop.

You noticed this issue early enough to manage it with neem or Pyro. I wouldn't stress too much. Take em out and treat them all over, once again in a week or two, but stop before you are too far into flowering. They are a pain in the arse, but not the end of the world. Check new grow for improvements and from here on, stop bringing pests into the grow room.
