Desired Parameters for Live Plants ?

I've been doing weekly water changes and just recently added in some new plants to give this a try again. Now I know my method this time for dosing dry ferts is wrong but I did the pinch method cause I'm too lazy to dilute it down.

I waited 2 days to test my water. My ammonia is between .050 and 1.0 ppm and the nitrate is between 0.0 and 5.0 ppm. It's hard to tell exactly...I would say it's about about a 4 actually. And nitrite is a 0 ppm.

Now my question is are these three test worth a flip for plants or am I barking up the wrong tree? If these aren't the test I need to be doing, which ones should I be? Where can I get a test kit that is the most useful for plants?

Are these levels too low or too high for plants? I'd really like as much input on this as I can get so hopefully I will have some luck this go around.

Well I'm just a rookie here, but from what I've read, ammonia is good for plants and very bad for fish. Nitrite is bad for fish and plants can't do anything with it (not so sure about this) and nitrate is not so bad for the fish and really good for plants. Most people here dose nitrates, phosphate and micro nutrients. There are other macro-nutrients such as calcium, magnesium and potassium, that you may not get from your tap water. Some of those you will probably have to dose.

I would do some more research in this forum. There are some other great resources out on the internet, such as the barr report (
Just check around some and you will get more information than you need
