i'm going to go against the grain here and tell you that you are over watering your plants and they are going to end up with diseases and blights. even here in the summer where we went almost 40 days with no rain i only watered 4 times. just once a week. you want the roots to grow down in the ground to look for water not up towards the top of the soil, which is probably whats happened and the reason your plants aren't getting all the nutrients they need. if it doesn't rain in your area water deep once a week, if it rains in your area you don't really need to water. get some organic fertilizer and get it on the plants as soon as you can and then stop watering lol. if you have blossom end rot miracle grow makes a specific one just for blossom end rot. as stated its a lack of calcium. if you cheap or poor like me you can make a mixture of epsom salt and water and that will help out a lot. good luck. i wish our growing season went into November lol. my tomatoes all have blossom end rot now and most my plants except peppers, tomatoes and cabbages are dead. though i did have a great year in the garden so I can't complain
