SDMN2 Blueberry Auto (1st FIM)

So I watched my first Blueberry Auto from Seedsman shoot up and get a foot tall in a couple of weeks so I decided to use this strain to give the ol' FIM technique a try. Familiar with topping from my OGK manifold that I am about to chop. I have no HST experience at all with autos and I always want to experiment so I'm gonna kill two birds with this one and pop my FIM and auto HST cherries at once. This one seems to be having a slower start which would be my luck but we shall see....
