You have a good understanding of the problem and possible solutions. Miracle Grow will give the quick boost you are looking for. Over the long run use any of the other materials, which break down more slowly.

nitrogen is very mobile in the soil therefor can change very fast. most places don't even test it because of that. but if you need to kick your plants in the hind end with some nitro if it were me in my soil I'd get grass fertilizer, but be careful what you get, you don't want anything with weed control in it as that will hurt your plants. don't get the time release stuff. I got some for my corn it's 34-0-0 you put water on in it melts and it goes to the plants that way it don't last long . that being said if the old leaves aren't yellow I wouldn't fret to much, there may be more going under the soil than you think. that's just me. wait for others to answer to do anything.

The ammonium sulfate is a good choice. It will give you the nitrogen boost and help keep your pH slightly lower where vegies like it.

thank u all for your help. and no angel i dont have any yellowing of the plants. i was just concerned cause of the recent halt in growth.

as far as the ammonium sulfate? how much should i use? im real scared to mess things up. just trying to learn about gardening trial and errors. but dont want the errors! HAHAHA ! God Bless Ya'll

ohh, i wanted to ask also what would to much P and K do? as if i used the miracle grow 18-18-21 on my situation (already havin' low N and high P and high K)
