I planted a hedge of twelve ficus nitida 15-gallon plants, been in about a week. I just noticed a pest infestation on the leaves, brown spots, some lumps on the underside, some curling, is this a thrip infestation? I don't see any actual bugs.
What is the best way to control this? I have read that keeping them watered helps them, I water them daily, also read that a soil drench with medicine can help control the pests
