When I did a flush yesterday I noticed that due to the increased root density in the pot it takes 5x longer for it to drain out to the bottom. Something to be mindful of when you are flushing.
I flushed my plant 2 times yesterday, it was starting to show signs of nute burn and possible lockout. I am going to drop my EC down between 1.2 and 1.4 until I flip her to flower. It seems that anything over 1.6 isn’t making my plant happy.
