The lowdown- newish plant. Acquired (or shipped with) spider mites (first time dealing with spider mites!!!). I've been heavily treating ALL of my philodendrons, including this one, and this particular plant is the only one I had to cut away the affected leaves on because they were too far gone- leaving just a small totally enclosed growing leaf. Once it emerged a day ago, I noticed it has a lot of these little white specks. I don't see any spider mites.. before I could hold up the plant to the light and see them move on the leaves I chopped. Is this a sap issue or pest or what?
Thanks for any advice!
