If I'm going to make this work I'm going to have to get better equipment I think. I'm down to 3 plants now. 2 are looking pretty good, although they are real light green in color. The third has been the runt from the get go although it's still hanging in there, not sure for how long.
NO nO No...I bought one of these...read it again.

It's a great deal...BUT, It only reads to 999ppms...that will get you through veg...pretty much. unless you juice them...would be good for seedlings and clones on light nutes, or as a 2nd meter for same reason.

You need on that reads at least 2000ppms or more.
If you can get milwaukee tds or EC meter...you would be better off. hope this helps ya
