I grow tomatoes, peppers and cucumbers but I am at a loss as to the type
of fertilizer to use and how much.
Every one sold in the gardening centers has a different ratio and they all
claim to be the best.

A soil test (about $15 give or take from your county extension) is the
best way to know "What to use" and "How much". Otherwise one can only
guess and hope for the best. Tomatoes like a pH 6.4 give or take 0.4.

One could go with shovels of compost around the plant two or three times
for the season. Compost also varies from place to place.

Too much nitrogen may give you all nice looking vines and no fruits.
So follow the instructions on the bags. N-P-K = Up-Down-and All Around.
