I dont bother to flush and pk really works well just be careful strong stuff .Considering that i'm in the transition phase and in the next days i'll have to start with bloom nutes, do u think it would be better to flush em or nor?
I saw u didn't with AGOGs.
P.s
I bought Canna PK 13/14 too...
As always i dont follow there guid of feeding .
What i do it once buds start hit them light with it just once then i hit them for 2 feeds in a row mid bloom medium strengh then just before i start to flush i give one last big hit
