Hey all, Great info on this forum and some amazing grows!

I have a question about a PPM meter.

Currently and on my last grow I had some problems with yellowing leaves, Im assuming its either nute burn, cal mag def problems.

I am looking to get a PPM meter and dont know which route to go.

Any suggestions on which work the best for the money? I cant spend too much I just bought a 600W Galaxy.

Any great sites or ebay that have the model I should get? Any links would be more then appreciated!

PS- If you have a chance please look at my thread in plant problems I have pics and everything I cannot figure out what is going on.

(I did a PH test lastnight (6.0-6.5) and today the first test showed 4.0 or lower. Then I stirred the water up and it was 6.0 +- a few points?) Its a wicking system with airstones. The res is very small and needs to be topped off every 2 days or so.
