See My Garden Grow

I surely would like your comments. These vegetables are growing in off-the-ground containers with plenty of drainage, soil, etc. I am using Miracle Grow's new spray on fertilizer every 7 days. I am also spraying for disease and bugs every 7 day. It has rained a lot. However, the tomato blossom are not turning into fruit. There is only one tomato per plant. These plants are specific to Texas. They are Celebrity and Early Girl, with one Sugar Grape. I do not understand what is happening to the blossoms to cause they to not pollinate. Any suggestions would be appreciated. Thanks!!
