Is there a good plant fert test kit?

Is there a good kit that checks the levels of all the nutrients I need for my plants that is below or around $20?

That's a pretty tall order, the only test that comes close to that is Nitrate. Phosphate and Iron can be tested but is quite expensive. Potassium probably is the most difficult to test but doesn't really require testing.

Take a look here for a list of tests and their applications.

its 40 there but you may find it cheaper and bigals will price match but that is a good test kit and has everything youll need pretty much for a planted tank.

well, you should already have a FW master test kit, so pH, Kh, Gh, ammonia and nitrite are covered.
So then you just need Nitrate and Phosphate kits. The only reliable and inexpensive Phosphate kit is SeaChem, and it runs about $10.
I use AP's nitrate test kit, it should be under $10.

No need to buy an iron test kit. None of th einexpensive ones will read the low levels we need anyways, so its a waste unless you wanna drop $40 on a LaMotte iron kit.
