My Blue Cheese has started setting budsites, my Bakerstreet is stretching, grew about a foot in the last two weeks, as has my Bakerstreet/sativa cross. From the looks of your pics yours are just starting.

Doesn't look like she is blooming yet, but she is definitely showing she is mature and ready for it as soon as the lighting is right. How many hours of nighttime do you have right now?

15 hours of darkness

When that gets down to 14, blooming will start

Since it’s outdoors, when during August will it start? I live in Southern Ontario, Canada.

You live in the same area as I do. Last year my outdoor plants started shifting into flower around now, as did my neighbour's plants.
Looking perfect great job!

Would it be wise to start using my bloom nutrientS? it’s organic, the blend is a 6-2-12 .I add NPK RAW cane molasses Too? Any thoughts? Would it speed up the transition into flowering?

Im north of lake ontario last year I had buds visibly started by Aug 15th. My cbd is flowering now the others are not far behind.

CriticalPurpleKush not flowering yet but the way its growing its not far from bloom subtle changes are getting more noticeable in the way its growing.

I would wait until the stretch is over to switch nutes, they'll still need the nitrogen for a bit. When you have flower formation like @SmokeLake has in his pics is when I would switch. Indoors I always gave my girls veg nutes for the first week or so after flip. This is the same idea.
If your going to feed Tiger bloom which is what i use you can start that now it has enough nitrogen to sustain vigorous growth.
I am also feeding Jobes organic tomato.

At 6-2-12 it should have the nitrogen for the stretch I think, it should speed up flowering a little just from the pk I think but it more matters on the sun. Some of them don't look like they have anywhere to stretch those are nice plants

Hi Canadian Bacon, I'm growing outdoors a bit to the South from you, in California. Yours may be heading into preflower, at least some. I didn't see pistil growth, but you may have bracts there, in which case pistils are not far off.
Mine have been in preflower for several weeks and just the other day saw I now have pistil growth on 4 plants. The first to flower was my Acapulco Gold, and she had pistils on July 10. The others (Super Lemon Haze, Blackberry and Dream Berry have put out pistils this past week. So different strains seem to start at a different time or take longer to put out pistils, haze strains can take longer to start pushing pistils. Check out my 2020 and 2019 grows (below). Emilya said it well: When you get down to less than 14 hours of daylength, flowering is not far. I've followed that advice for years now, and it is true. I'll go one further: When the daylength is shorter or less than 14.25 hours (14 hours and fifteen minutes), then flowering usually starts about two weeks after that. There are sunrise/sunset meteorological websites that will tell you what your effective daylength is.

I can't help but wonder if it's more about the change in day length than the actual hours when you're outdoors.
In Los Angeles on the summer solstice they get 14 hours. How do plants grow there? 2 or 3 week veg then straight to flower?
Up in Alaska, or the Yukon they will have 16 hours and 45 minutes of light mid August, are outdoor plants going to wait for 14 hours of light to start to flower? Would they even have enough time to finish?
Do outdoor plants up there finish around the beginning of October?

The extreme climates can lend good insight. I don't know when flowering would start in Alaska, the days up there will shorten quickly in September. I've grown in Northern Europe, and harvested many strains in September and October. On one grow there, I harvested November 21, that was GHS Arjan's Haze #1, harvested after the snow had started!
At one end of the scale, you've got sativas growing in the tropical regions and in the equatorial zone, where the day length hardly changes at all and the native plants there take a very long time to ripen. On the other, indicas in the Himalaya, in comparison, have a shorter growing season and have evolved to ripen earlier.

I guess the only way to find out would be to ask an indoor grower to veg some plants 18/6, then to start decreasing the lights on period by the same amount as your day length decreases every day after the solstice. It starts out decreasing by a small amount, then decreases faster the closer you get to the equinox, and the farther from the equator you are.
I mean on the solstice in Alert (the northernmost permanent human settlement in the world) the day is 24 hours, and the equinox it's 12.
For where I am the change in day length for the 3 days after the solstice I get -1 second the first day, -5 the second, -9 the third. Then fir the 3 days before the equinox in September it's -2 minutes 55 seconds.
So you get the indoor grower to match the decrease day by day and to mark down when the stretch starts and when pistils appear. You get another grower to match the day length changes for somewhere else, and compare results.
For what it's worth the day length today for 43 degrees North (Southern Ontario) is 14 hours 26 minutes.

My grow in Europe for years is at 47N. Flowering can start as early as mid-July for an early flowering strain. Indicas like RQS Critical flowered in August. But most strains start around September 1. Last year Arjan's Haze #1 didn't start flowering until October. So in part it's strain-dependent. Within each photoperiod strain, it is dependent on daylength.
