20-20-20 is fine, I would use that at a maximum of 0.6tsp per gallon with a monthly flush of plain water, or you could go down to half (or even less) that at every watering.
If you have others you can use them up, that's what I would do, but calculate the mixing ratio based on the nitrogen value.
For the 11-35-15 I would go with a max of 1.2tsp per gallon (with a monthly flush) or half (or even less) with every watering.
For the 35-11-15 I would go with a max of 0.4tsp per gallon (with a monthly flush) or half (or even less) with every watering.
