Planted 4 Bonnie patio tomato plants in

[Shooter1103]

5 Gallon buckets with holes drilled in the bottom for drainage and a couple of inches of gravel in the bottom and a layer of Heavy duty landscape cloth on top of that then Miracle Grow organic container soil which states up to two months of feeding in soil. I planted these healthy looking Bonnie Patio tomato plants 2/3 of the way into the soul leaving the other 3rd above the top of the soil. I also put some egg shell calcium I ground from organic range fed chickens and ground into a fine powder in the planting hole and some Epsom salt as well. The plants are loaded with flowers and some tomatoes up to small baseball size but the plants are not growing in height? Growing outwardly but not much in height. Any suggestions on how to get the plants to start growing vertically and get the actual green tomatoes to start getting larger as it seems the are really slow in getting any real size to them. I water everyday except when we get afternoon thunderstorms, and have small tomato cages pushed down in the soil for support? Also my plants leaves seem to begin to start turning yellow and brown late in July and August, anything I can do to prevent that this year? I am a total rookie at this and had decent results last year with my same set up. Used container organic container soil from Miracle Grow this year and added egg shell calcium and Epsom salt in the hole this year when planting, so need to try and keep the yellowing and grown leaves away this year and keep the plants nice and green like they are now and producing tomatoes long into the end of August and September. I would appreciate any and all help but please keep it simple for this rookie non green thumb Gardner. These tomatoes are on wood blocks for better drainage and get plenty of full sun daily. Thank you in advance for your help.
