Tomato seedling - possibly disease?

Hi there, I started quite a few tomato seedlings indoors in late February under growlights. They have been growing quite well and overall look healthy. Recently however, I have noticed some spotting on a few of my tomato seedlings. I am worried about what this is. I’ve attached some pictures here for your reference. Anybody know what this is and what I should do to mitigate it? The rest of the foliage and plant is quite healthy. Thanks!


It seems to be either a disease or a problem with pests. I see some black spots on the leaves, what could that be?
Have the transparent spots got bigger or changed color?

I recommend you try the Click and Grow Smart Garden for starting seeds. :slight_smile:
