The warm is here is it i'm over/under watering?

[baisla]

I Started few days back vegetation in a green house, then they were replanted on 4/10. I select all complete sun fresh vegetables. My vegetation are properly watered by a landscape sprinkler at 11pm. They look dry so Ive been irrigating them again between 12-3. Could I be under irrigating them? New to farming.
thanks
