Thanks, I already have Cherry and Beefsteaks and tons of flowers too, I hit those containers weekly with 2 ozs of liquid cal/mag+ made by Botanicare, They need a lot of supplements on the uptake in this growth period before flowering, I also mix in a cup of dolomite lime into the soil before planting, As well as a 2x2 strip of 10-10-10 fert, That prevents BER, (blossom end rot) It may also be the variety you have planted, I prefer the beefsteaks or better boys, Its more of a firm tomato which are great for burgers or sandwiches as well as marinating them.
