Chow_13answered grow question 3 years ago Its hard to tell but to me it looks like thrip or leaf hopper damage. Is your grow outdoors? Carefully inspect the underside of the leaves. thrip will be small worms that dont move before they grow into fast moving bugs. Leaf hoppers look like little grasshoppers. lay down some sticky tape and see if any bugs get stuck on it. The damage looks minor right now, But its best to find bugs early before they become an infestation.
Happy Growing.
