I’m not home right now to make better pic but it’s not automatic flower so I think she shouldn’t start when time it’s still 18h she is only 5 weeks now. But I’m afraid because she get little of light when supposed to be dark. Maybe couple min it was but it could be a reason? As soon as you see balls, end the process. you waste resources, time and effort in vain.

" Pretty unlikely, more often that'd prolong the flowering, but if it's only a few minutes shouldn't do shit. Even if it does upset the plants (unnecessary stress)

You can't really see anything yet, it could be about to start, you should check the nodes on the trunk like @Sir_isO says. I also see excess of what could be nitrogen, nothing serious, but keep an eye on that.

I mean, I can't tell if those are pistils or not, from the photo. Is that shit white or sort of translucent?

Doesn't look like it, take a few photos of the nodes by the trunk, there should be some pistils.
