Of the 2, the 13-5-11 would be a much better choice than the 13-13-13. If you were using only a CRF as your nutrient source, I'd suggest you use about 1/2 cup/cu ft of soil, which comes out pretty close to a tbsp/gallon, but if you're using it as a back-up, I'd guess you'd probably want to use some fraction of that amount - up to you, but 1 - 1.5 tsp/gallon sounds reasonable to me.

Hello again,

Thanks for the info. I just have a few more questions. I actually just received my Foliage Pro shipment. Would I be safe fertilizing them weakly weekly with 1 tsp per gallon of water? Is that the amount you would recommend? Would that be the same ration with my vegetables in half barrels?

Thanks again,

While air temps are between 60-80, I usually fertilize at 4 tsp in a 2-1/2 gallon watering can, which is about 1-1/2 tsp per gallon, and I see no evidence of plants having trouble keeping leaf margins & tips hydrated (no sign of fertilizer burn), or any sort of sense that the plants are being pushed too hard, so I think 1 tsp/gallon on a weekly basis is well within reason ..... if you are watering copiously so the soil is being flushed at each watering.
