I Started Tomato Plants From Seed, Some Of Them Look Great And Some Started Curling In The Top And Are Stunted. What Causes This

Question

and can it be corrected? I used rich garden soil and put them under grow lights in the sun room but they were crowded.

Answer 1

It could be due to too much nutrients in the soil, overwatering, overcrowding, or too much/too little lighting. Unfortunately, your photos did not come through, so I am unable to assess the damage, but those are most common issues resulting in curling.
