Help! Brown spots on seedling leaves
I planted these tomatoes about 4 weeks ago, they are kinda leggy and grumpy in general, but I have gotten a good germination rate. Now their little leaves are coming in, which is very exciting, but the seedling leaves are turning yellow and have brown spots on them (see picture), is this normal? I just want to make sure I diagnose any problems before I lose any plants!
Right now they are in partial sun (should I put them in full?) and I keep their soil very moist at all times.
Is it time to transplant? They are still in their original seedling mix (i think it was jiffy).
