I ended up losing several tomatoes to blossom end rot. I had fertilized with a cal-mag supplement but the tomatoes were still inside then and I was out of room so they stayed in very small containers. I believe that was the problem. Now they are in 5-10 gallon containers and they are very happy. My question is do I let them dry out between watering? I tend to pick up the pot and see how heavy or light it is and water accordingly. I don't let them dry out and I was thinking that might not be the best approach. Advice? Thanks!
