That is very weird as tomatoes love sun and produce faster and more on sun. Does rain shower the small ones by any chance?
Edit: also it could be to hot for growing tomatoes already try putting them inside for a bit? They look small for this time of year when did you plant them?
Do they get more sunlight or are less exposed to elements? Anyway i suggest you have them in a place where rain cant get to them as acid in rain can destroy leaves, also plant a basil with them its a natural pesticide for tomatoes.
Wait so geotips isnt the most hated site anymore, right?
Looks beautiful, love how different the mountains look from mountains here. Can't imagine hiking in such heat though.
