This far along, I'd be wary of opening the fermenter. Picking up and swirling the whole thing can be tricky with a PET fermenter. Start small and increase the swirling motion as needed.
The picture of the krausen was from the 3rd day of fermenting just to show how small it was - hasn’t been any krausen in like ten days. Definitely gonna give it another week though.Swirl it a bit to get some of the yeast back into suspension, but give it time. Since there was still a 1/4 inch of krausen, it will probably drop at least another couple points. WLP002 (if that's the one you used), will crash out fast and hard when no more CO2 is rising up.
Brewfather defaults to a boilerplate yeast with 75% attenuation, so your FG will go up if you add a yeast with lower attenuation to it. I assume the Grainfather app is the same.This is odd . So I got 1.011 , then realized I forgot to add the yeast. When I added wlp002 it shot the FG back up to 15???
