Still waiting on the nutriments to arrive as well as the light.

ppm filtered tap water 195
ppm hydro water 295

I am using a HM Digital TDS meter model TDS-4

Is there a tool, or do I need a tool that measures each amount of Potassium, Nitrogen, and Magnesium and other similar things?
PigSnout Reviewed by PigSnout on . Hydro Set Up This is a great site. Thanks to the mods and all the members who dish out the information. I have a NFT System, 18/6 for lights and water pump. Growing Northern Lights in one net pot and White Widow in the other. I have 2 setups. The first one is already going using the nutriments that came with the kit. TDS meter is on the way so I can actually measure what is in the first grow. Four small containers with no info on what is in them. Just the words Base, Bloom, Grow, Catalyst. A guide Rating: 5
