im no expert but i belive the higher nitrogen fert would give more green growth and the other would give better flower and fruit production.. i would use the 5-10-5 on most of my garden and the other i would prolly mix weak for spraying seedlings or watering in transplants but like i said im no expert im just learning this stuff too

Then both have the same nitrogen content, and the one has a higher phosporous content. When deluted and sprayed, it delivers small amounts of the nutrients, just enough to act as a "booster" to supplement what the soil is providing. The chances of adding to much of either is almist nil, so I would go with the one that also provides phosporous, but either one is fine for a plant boost!

Which to use depends on what your plants might need. The 5-1-1 will give the plants a Nitrogen boost that could give them lush green growth and no production while the 5-10-5 could be somewhat more balanced if your soil lacks some basic nutrients. What do your plants look like? Are they the green color they should be, or do they show signs of chlorosis, yellowing? Are they a nice green color but stunted in growth? Are they producing as they should?
Only for the first seven years, until my soil started to build up some humus (after I discovered that tilling was not good) I did need to supplement feed the plants I was growing but once the soil became balanced from the applications of compost and mulches no more supplemental feed was necessary and could have created an unbalanced nutrient level that would have made the plants more attractive to insect pests.
