@ScotlandDrGreen420, oh yeah didn't noticed , either ways man , from my experience and my basic knowledge , flushing should affect lower leaves first and not by sharping the edges , curving them and burning the tips ; but by taking away the color since the plant is " eating " the nutrients from their leaves; hope that helps , but I might be wrong since I have never had any experience with hydro grow and could be different maybe.
any ways , hope your grow goes the best way possible 😬
