Growths on tomato leaf

Question

Can anyone explain what is happening with my Big Beef tomato leaves? All along the leaves there is these new growths starting. Never seen anything like this before and grew the same kind (supposedly) of tomatoes last year and they did not look this way. They are in greenhouses grown both hydroponics and soil. All the Big Beef are looking this way. I am not sure if I should prune them off or let them grow. If left to grow they will become a new runner with blooms. Just never seen such a growth on the leaves themselves.

There is a tomato leaf curl virus. There are other possibilities, discussed in this article: https://www.gardeningknowhow.com/edible/vegetables/tomato/tomato-leaves-curling.htm
