Help! What is this?
First off, I'd really like to thank everyone for helping me with my first experience as a gardener...you've all been great.
So here's the problem: several days ago, this weird white dot appears on my tomato seedling. Today I checked it and it got worse. It also appears like another leaf is contracting the same problem. I had a tomato seedling that experienced the same problem 2 weeks ago. The leaves would contract that white dot, turn yellow and shrivel up. I removed the leaves and it's barely hanging in there, but now it's happening to another tomato. Thoughts? Fungal? I wait until my mix turn dry (finger test) before watering. Kept inside under lights. It's also fed with kelp powder.
