I should stfu but it is what it is, I’ll happily stand corrected.
I broke a branch tight to the stem nearing the end of a crop, i got a strip of capillary matt and used it to siphon sap from the plant over the course of lowering the nutrient and measuring the ec, i found it fell in line then to 0.0 with water.
Jfc i don’t subscribe to flushing, however I couldn’t overlook the nutrient the plants pull up before they’re chopped ie the nutrient is spread around its vascular system, typically water evaporates leaving its mineral content behind that’s what I see happening hence the 3-4 days water.
I’ve had enough pelleters at Riu ffs go easy
