Not sure where you're located, but in my area flowering won't start for another couple weeks. Those look to be preflowers, just a sign of maturity and sex. I could be wrong though. There's not much to go off.
That's just preflower. Those are pistols showing and no formation of buds. They won't start forming buds unless the light cycle changes or they go through some sort of extreme stress. Using flowering nutrients is a little premature at this point unless your natural light cycle has changed enough to enduce flowering. That's all going to depend on where you are, but at this point those are not flowers.
This is something I have been worrying about for the last couple of weeks. My backyard is pretty small so the space I can allocate for a big plant like cannabis is limited and living in a pretty urban area there tends to be a lot of lights outside at night.
I would suggest getting strains that are shorter or autoflowers that hit medium height or create a autoflower version of your favorite strain to open up the genepool more or if you create a photoperiod strain . You can make a autoflower version of it also . because sativas are great to have but not in your situation people usually top the shit out of outdoor strains . or keep training in a bunch of layers of some sort of scrog nets
I grew a few autos a long time ago and they were not too bad. This was a long time ago though and from what I have seen it looks like they have improved drastically since then. Sugar Black Rose by Delicious Seeds is the strain I am growing (Critical + crossed with Black Domina). It's one of my favorite strains by far but I don't think it is too popular in the north east. My neighbor has been growing it for years outdoors and it's pretty stabilized pretty well for our climate and has great mold resistance which is a great trait to have here. A lot of times it tends to grow more wide than tall but it can get tall in some situations. I have topped it multiple times and I am doing some LST also. I wish I could scrog it but unfortunately I have to be able to move it once in a while. If I could figure out a way to scrog and still be able to move it once in a while I definitely would.
