HH, sorry about not getting a pic to you last night. I have a newborn and it's tough to find time. I checked mine out for a second and it looks similar to yours I think. I honestly don't think the door being open has to do with it, unless it has been open a ton it probably wouldn't slow the ladies down. More likely is the heat. It seems rather sensitive to heat and any plant will slow down with the temps you've been having. I think you'll be fine.
Don't stress too much, those ladies will reward you. The final buds are not huge anyway, but dense. The weight comes from the density, they are little rocks that don't harden until the last few weeks. Og's aren't big yielders anyway and they are different than most pot. It grows more viney and slower to develop.
I'd say you have a combo of things going with heat being the first and just the strain's normal characteristics being the other. If they are being stared at during lights off, that couldn't help either.
