Hi! I make my own pest spray, it’s neem oil, peppermint Castile soap, hydrogen peroxide & water. When using on my plants do I have to wipe it off after?? Or can I just spray and be done? Also, I noticed this yellow spot on my manjula pothos that I’ve never seen before. This plant has always been super happy and pushes out tons of new growth. I repotted it about a month ago. What do yall think caused this yellow spot? Thanks in advance!
