I have planted 2- celebrity and 1- 444 and all three plants have some leaves turned and turning brown, ugly.

These are in a new raised bed built this early winter. The soil was purchased as "veggie mix" which is just mixture of sand and compost,
I feel like more sand than compost.

Do you think my tomatoes are doing bad due to "veggie mix"?
What should I do to better my veggie mix for new tomato plants?

Help! I want tomatoes!!!

how often are you watering? Make sure that you soak the plants then let them dry out a bit before watering again. Poke your finger down into the soil to test for moisture. I plant in 100% compost with green sand and lava sand mixed in.

I water about once a week. I will amend my raised bed with compost
and green and lava sand. thanks, sandih for helping.
