I have found some tiny white-brownish little bugs at the base of my plant, they are not springtails as they don't jump around but they do affect the plant a little bit as it has brown spots on the leaves, they are microscopic small as I tried to take these pics whith maximum zoom from an S9 on another phone's screen so it can be black sorrounding to maybe have a shot, the piece of compost in the picture I had to take it with the tweezers that's how small they are and one of them was on my finger it was almost transparent compared to the color of my skin, Could it be aphids or spider mites? I tried to spray them with neem oil but applied it every 2 days for one week even in larger ammounts than what the instructions said and tried some bugs repelent as well but the little fuckers are still there and still making my plant sick, do you have any ideas?
