Any gardeners out there? Help using dry ferts for tomatoes
So I have a nice little garden box going with seven tomato plants. Before I did any research I probably made the initial error of over fertilizing. I was using water from my tank that I dose EI because it seemed that would be the best water being that it is saturated with nutrients. Well the plants definitely took off, but then I started doing some more research. Turns out tomatoes don't need high nitrogen and dosing as such will result in beautifully lush green plants, but no tomatoes.
I stopped dosing and just resumed watering which I learned would flush the excess nitrates from the soil and have since seen over ten tomatoes growing now. I went ahead and did the trimming of all the branches below where the plant was flowering as I learned would better induce fruiting.
Now my question is can I still somehow dose any of my dry ferts such as potassium and phosphate? I read that once you start getting fruit you should fertilize once again. So is there anything I can do apart from getting actual tomato fertilizer? Does anyone have experience using our normal dry ferts in their gardens? Please leave some insight, thanks!
Box is 8'X2'X1' and has about 12 cubic feet of soil which somehow nearly fills this box which is 16 cubic feet.
