I'm a beginner gardener growing tomatoes and peppers from seed for the first time. I need some help diagnosing a problem on the base of the stem of most of my plants.
I've been watering my plants once a day during the last month and a half. I started watering on top and then switch to bottom watering (I provably over did it).
I've checked the root systems on one that recently snapped and it just looks really healthy so doesn't seem to be root rot.
To my newbie eye it seems I have some brown fungus on top of the soil and it's just eating the stem.
Any ideas of what I may be facing here?
