I have a Tomato Grafted Stargold F1 (Yellow Cherry) growing in my greenhouse. It has been in there for several weeks and it seems to have grown taller but all the leaves are very tightly curled in.
What could have caused this tomato plant leaves to wither so, and get not discolour?
What could I do to improve the tomato plant's health?
The neighbouring tomato and pepper plant seems healthy. The plants are in the greenhouse soil which is fresh garden soil and well-rotted horse manure. I have not started feeing the tomatoes yet, as they do have any flower or fruit started yet.
I had not pruned any of the plants yet. This morning I pinched out the extra shoots. I would estimate it like the other tomato plants are twice the height they were.
