I planted various tomato’s about a month and a half ago and have had great results until recently. This particular tomato (an heirloom variety, specific type unknown) began to have curly leaves and has not grown much in the past week or so. There is no discoloration or signs of pests otherwise. Any idea on what the cause of this is?

For reference, zone 8b, watered 2-3 times a week.
