I bought a monstera off someone who said the plant needed love but had no bugs 3 weeks ago, she mentionned she work out of town so the plants go weeks without care.Anyways, I put it in quarantine in my bathroom which has a skylight.I'm kinda new to plants so didn't really pay attention to the leaves when I got it but I did notice there was tiny spots on the leaves. I don't think it is getting worst but there is like tiny bruises (most don't so fully through the leaf). The leafs also seem to have a silver discoloration which from what I read seems to mean thrips?Ive been treating it with a neem oil and dr bronners spray mix every couple of days. I have been inspecting the leaves pretty much every days for about 2 weeks and dont see any bugs.Ive also put DE on the top layer of soil in case. Maybe regretting that decisions now?Should I be worried?
