Hi,
This is a cherry tomato plant. The leaves are turning brown. I have no idea what is the issue. Please let me know, what needs to be done to stop it.

The tiny pin points of white as seen on top of the leaves are usual indicator of sucking pests congregating on the underside.

I’m tempted to say whiteflies. Have you noticed tiny white flying insects that fly up when disturbed — when you walk by or touch the plant?

Look underneath those leaves. Look for concentric circles of tiny white dots — whitefly Eggs — in addition to the adults which are pure white tiny winged pests.

Not positive what the browning is from, though I have a vague recollection of this happening to heavily whitefly-infested leaves. They can also be carriers of viral and bacterial diseases, there is that possibility as well.

I did see white stuff. Didnt think much about it.
