Hey I was wondering if anyone has any experience with testing brix levels with a refractometer? How is it done, how does one test a shade leaf for brix levels? And if anyone had any suggestions on a good not that expensive refractometer? I appreciate the info guys. Edit: Found this. Not so sure how accurate it is. https://www.maximumyield.com/building-up-the-brix-for-healthier-nutrient-dense-crops/2/1282 Also I watched a YouTube video on using a refractometer, and you just crush a leaf until sap comes out which a refractometer can read?
