Okay newbie here having trouble with conversions. Let me explain my set up first. I am using a recirculating system with Canna Aqua nutrients. I have a Hanna Combo Ph/EC/PPM Meter (the black one). I also have questions about adding my initial PPM from tap water. Here is what Canna says about Aqua:
Seedlings EC .7-1.1
Veg phase 1 EC .9-1.3
Veg Phase 2 EC 1.2-1.6
Flower Phase 1 EC 1.4-1.8
Flower Phase 2 EC 1.6-2.0
Flower Phase 3 EC 1.0-1.4
Flower Phase 4 EC 0
Now Canna says they add .4 EC into these numbers for tap water. Do I do this? I'd like to use PPM. My tap water is 210 PPM.
Canna also says they convert with a .74 conversion factor. Please Explain. I know there are different conversions which is confusing, but my Hanna Meter is EC 1.0 = 500 PPM. I do not think these are compatible because a .74 conversion factor would be EC 1.0 = 740 PPM.
I basically have to modify Canna's recommendation from .4 EC to .2 EC?? Then I have to somehow get their PPM Conversion to Hanna's .5 conversion??
What the Heck is going on here? I'm so confused. I don't know what to do to get an accurate reading/ feeding schedule. Please let me know if I should add my tap water PPM to my recommended PPM and include it. thanks
