Ya well that's the same process I pretty much do. I stop feeding weeks before I am about ready to take them down. I consider that a flush as well just because you arent feeding the plant anything except water. I never looked at it as a fade but can see why it would be called that.
But Ya I feel flushing dumping tons of water through your plants is kinda pointless unless you are trying to correct something.
No worries man, i was just going into alittle more detail for guy asking.
