Before I read any further, the question to ask is "at what conversion factor is the 1430 ppm referenced?" I guarantee it's .7 which is slightly over 2 ec and acceptable.
So if using a .5 meter we would be at the same ec at 1000ppm. EC is the true important number as such. We always refer to ppm though.
Since learning about this I have made it a habit to state my ppm as: 980 ppm (.5 conversion). for example.
This way a person here using a .7 meter could easily do the math and see I would be at almost 1400 ppm on his meter. Now we're starting to speak the same language and can offer better qualified responses.
I wouldn't worry about the fact you have a .5 meter. Lots of folks do. And they work fine in their grows. I really dont think it's that important it needs to be .64-.7 conversion or whatever they said. So long as we use the conversion factor properly.
Yes, I agree. Problem is my meter has a floating calibration depending on what calibration solution I use. I really need to call them and get this explained to me a little bit better.
