My tamaydas are not doing well either...at first I thought it was due to my new gardening method. Not so. As I look at everyone's tamaydas all around me, I notice lots of nice, green leaves, moderate height, very few tamaydas and those that they have are small. Much like my own.
Last year I had tamaydas like gangbusters...HUGE and plenty.
Too much rain, not enough sun in these parts. Now we enter August, when the rain is stopping and hot days are here~sun finally makes an appearance~ but the plants all have shallow roots due to excessive rains all spring and summer until now. Many plants have blight, fungus, etc., but now they will deal with no rain...they will die.
What I'm seeing in my own garden are some plants dying and tomatoes that fail to ripen, blossom end rot here and there but overall, not a good year here for tamaydas.
For the record, that's how I say tomatoes also....tamaydas.

Must be a southern thing....
