Hello everyone, I have run into a problem and hope to end it before it begins to damage the plant. A friend of mine planted a seed he found in his bud a while back, not expecting much to happen. Now, it's three feet tall and in its very early stages of flowering. However, a problem came up... Some leaves are beginning to whither and small, irregularly shaped silver marks are appearing on the surface of the leaves. The mark does not go from one side of the leaf to the other, they are only on the surface. More and more of these marks are showing up as the days go by. He has noticed little flies which he believes are fungus gnats in the soil. Though, he hasn't found fungus gnats as the cause for silver marks on leaves-it is mainly due to thrips. Based on the pictures and description, what do you all think?
