Have these started flowering?

I have three plants (2 Cennex clones planted mid-May) and One Double Bubble clone (also planted Mid-May)

The two Cennex seem to be entering flowering, or maybe it's just vigorous veg?
It's seems about two weeks sooner than last years plants

Can you look at these and see what you think?

Thanks

looks like week one of flowering

Thanks, I kinda thought so, a few (3-4) larger fan leaves at the bottom of the plants have started to yellow, which I've always thought was natural for all plants. Otherwise they seem very healthy.
Could I be doing something wrong to cause them to start to flower a little early? They are getting direct sunlight from about 8:30- 6:30 and our weather has been sunny and lower 80's for a while now.

If they've just started flowering now, can I expect much more vertical growth from they in the next 6-8 weeks?

different strains tend to flower earlier then others, you probably just have a different strain from the one you had last year, totally normal.
i live in canada, and mine are starting to flower to, i wouldnt worry too much.
expect them to double, maybe triple in size.
