A month ago I sprayed all my plants 3 times with spinosad because I found a trips on one of my plants.
Today I found another. I sprayed these Kalanchoe Blossfeldiana propagations with 70% isopropyl alcohol and the rest of my plants with a home made spray ( "sexy plant juice" - 2 cups of water, 2 tbsp Neem oil, 1 tbsp peppermint Castile soap and a dash of isopropyl alcohol).
I waited for the alcohol do dry on the Kalanchoe and then I sprayed it again with the home made mix.
I will spray the Kalanchoe every 3 days with alcohol.
❓My question is : should I remove the severely affected leaves? I has 3-4 leaves like the one in the picture, the rest look ok.
❓Should I throw the whole thing away instead?
-------------------------
-the plant is on a balcony that is facing north. Good indirect light. I also bought a Sansi light 40w, it's on the way.
-terracota pot with drainage
-aroid soil mix not very chunky due to the size of the propagations
