The standard conversion scale is the 700 scale (or .7 scale, same thing). Because of the 3 different ppm scales, I only use EC as my measurement. It solves a lot of issues and I recommend doing the same.

Struggling with knowing when to waterFirst time grow, I am using the living soil autoflower mix, struggling to know when to water at the moment I have been feeling and adding 250ml every 2-3 days for a 3 gal fabric pot. Would a soil moisture meter work well to see?Week 2

We have decalcification machine. Should I add Calmag right from the start? How much? (Autoflower in mostly Biobizz Allmix)We have a decalcification machine (natrium based), so I have low magnesium/calcium. People say my soil is low in cal/mag. Should I add Biobizz Calmag on my first watering?(50% of recommendation for autos?) This one looks already droopy, doesn't it? Think I need to water soon.

Questions about wateringI created a 40 ml solution, the instructions say to transplant after the sprout has grown to the top of the plastic cover and the roots are visible through the plug. The question is, is 40 ml of liquid enough for this growth? I think not.
