Tomato and Pepper production slowdown
So I had a great start to the year - my banana peppers each supported ~40 peppers and the peppers were all a decent size and the tomatoes were doing pretty well too. But now my tomato plants have ceased production entirely and the peppers that are now growing (the large ones have all been harvested) are about half to two thirds the size of the first lot.
I'm growing in ~7 gallon containers. Soils various MG* types - organic choice and moisture control (in different containers). I've been fertilizing with MG 10:10:10 Tomato Plant food, using about a teaspoon of fertilizer in a gallon of water each time I water, about twice a week. When I water the peppers the leaves are normally starting to wilt just a bit.
The peppers look very green and happy, just with small fruit. The tomatoes are having a rough time and occasionally leaves start dying at the bottom of a vine before the dead leaves work their way up that particular branch/vine.
Weather has been pretty good, zone 7a. Lots of sun but no sign of sunburn on the peppers.
Am I fertilizing too much, too little, missing some sort of nutrient? I'm surprised at the productivity crash after such a good start to the season.
*This was my first year growing in containers, next year I plan to use some of the highly recommended home made mixes I've read about on here
