TOMATOE PLANT LEAVES | Vegetable gardening | GEEKGARDENER

Sir:

I have about eight pots in which I have transplanted Tomatoe Saplings.  The plants are growing fine.  However, in one plant the leaves become curved and the growth of the leaves are small.  What it could be due to and what is the remedy.  Earlier, six months back I had a good harvest of Tomatoes and did not have any problem.  Thanks.
