Lime added to the soil at planting time will help prevent blossom end rot.
Yup.
Lime, bone meal, wood ash, almost anything with alot of calcium. Fast growing veggies need calcium, it’s one of the triggers that help cells divide.
Good for lettuce, cabbage, broccoli also.
In general, if you need calcium, you probably also need magnesium.
The lime I get is about 2-1 calcium-magnesium.
Plants need magnesium to make chlorophyll.
