labifleanswered grow question 6y ago Hey gardener, first of all, if you have insect problems, you need to check under the leaves. I figured that out late, but that's where they hide. Then, if you find stuff under the leaves, you should normally treat it... except you have 4 leaves on each plant, so you take a cloth soaked in water or water and soap and wipe the underside of your leaves to kill the pests and their babies. No need to treat 4 leaves with complicated stuff. Otherwise, I've seen leaves grow as if they were being eaten, so maybe that's your case. Bella ciao!
