This gives a guide to how the mycelium will look when you make the 2nd application of MycroNutrient
at early pinning. In this case it is Day 10.
Application can range between day 10 and 12 typically. Bear in mind that it takes about 4 days to get into the mycelium and up into the mushroom.
This is a key time to apply whether you are on 2 or 3 flush system.
