Quoted By:
~80% of my pot grown roma tomatoes on all 3 of my plants have blossom end rot despite fertilizing them several times with dissolved limestone in addition to occasional 'vegetable garden' general purpose fertilizer.
I water heavily once a day in the morning and occasionally at night if I see that they're wilting due to the heat.
It's frustrating because the plants are big and beautiful, but I can't stop the tomatoes from rotting.
Do they just need more limestone? I've put several teaspoons worth over time into each 14" pot already.
