I have a bad ass video card and I can blow it up and see those little white dots on top of the leaves.
YOU HAVE SPIDER MITES!!! Dont be one of the peeps that think it cant happen to them. If you get any clones from anyone you need to protect you entire garden from them. You need a safe place for those clones you got firsthand to make sure thereare no mites, PM on them before you introduce them to your grow room and infest the whole room.
When I get new clones I bathe them in
Avid, and stuff for PM. I leave them in a seperate room untill I am 100% sure there are no problems with the new clones.
Take those out of your grow room ASAP, Go buy some real stuff to kill mite eggs and adults. You probably need 2 different types of Miticides to combat this.
I learned the hard way a few years ago and will not let it happen again.
You need to act fast on this as it will spread like lice in a grow room and ruin your crop.
Deal with it now before you have a infestation you cannot get rid of.
Dont be in denial about having Spider Mites and think you took care of them. Always expect you have them when getting new clones and treat properly.
Good luck.
