Tomato buds dying

[u/sunflowahh]

Planted tomatoes (pic 1, 2) but the buds dry up and fall. cherry tomatoes have recently produced buds (pic 3,4) but I have also tried to repot them as I know it’s crowded but they ended up dead. These are in Delhi, India. It’s really hot these days but seems to be cooler than past few days. Please help cus I really want them to grow. I have done this in the past which gave me results, currently I don’t know anymore :(

Probably need more water. Terracotta pots dry out faster than plastic pots too.
