I'm looking for a
nutrient solution for dummies approach. Where can I learn all I need to know to grow healthy plants? I have a conductivity meter and I haven't got a clue what it all means. I'm completely confused by all the terminology eg.) TDS, EC, CF, ppm, ppt, microSiemens, milliSiemens etc.etc. My meter reads in milliSiemens. Can I use this? and What would an ideal reading in milliSiemens be for my blooming nutrient, and vegetative nutrient. Please advise. Thanks much.
