Liquid Plant Food

I'm not sure in which section to start this thread, so I'm putting it in the General area. If one of you nice mods want to move it to a more appropriate place - go for it

A friend asked me when I fertilize or feed plants. I gave him my best advice, "Don't follow my advice because I don't know."

Well, I've been learning some, and am trying a simple test/experiment on what I have read

N = Nitrogen which helps stem and foliage growth.
P = Phosphorous which helps grow roots, produce flowers, and seeds.
K = Potassium which promotes the health of the plant - maybe helps disease resistance.

I chose to use MG Tomato food which is:

N 18
P 18
K 21

I've been using this on some our tomato plants out in 3 raised beds. I haven't used any plant food on the tomato plants in the in-ground garden. The plants in the raised beds are bigger than the ones out in the garden. (I should mention that the tomato varieties are the same in both areas) Apples-to-Apples comparison.

Now that the tomato plants in the raised beds are just starting to produce flowers and a few tomatoes - I was wondering about using a different tomato food. This one is liquid just like the MG, but it has different numbers:

N 15
P 30
K 15

Going by what I have read, it seems like it is time to boost the Phosphorous levels to help the plants produce more flowers and tomatoes.

I am curious to what you think on this?
