Help identifying the stage of flower of my plant

[Legended]

Would this be considered early bloom or mid bloom and should I uptake the phosphorus at this point? I've only fed her once so far just a few days ago with GH trio nutrients @ 2.5mL of micro / flora / bloom and 1.25mL of CalMag per gallon (3.79 liters) of dechlorinated tap water @ 6.4pH. I discovered the first white piston on the 5th of August, more than a week ago from today.

The strain is Banana Kush Auto. She sprouted on July 11th and have lived all her life outdoors starting in a 12 ounce party cup of HF. I transplanted her in late July to a 5 gallon fabric pot with 70% OF / 30% Perlite.

Weather has been pretty consistent, averaging at 85F / 29C @ 35-40% humidity during the day and 68F / 20C @ 70-80% humidity during the night.

Here's one of the lower colas:

She is just about to start flowering. If I recall the GH you are using has a "transition to bloom" feeding chart. I would say that is exactly what it's doing right now,, transitioning to flower. It's still going to require N, but your going to want to start tapering it down.

I fed her for the transitioning phase a few days ago at half the recommended dose so assume I'm on track with the feeding so far. What's a good indicator to start feeding her the recommended dose for the blooming and flowering phase; when trichomes are present?

I would guess you have another week to get a lil more growth out of her before her buds start to form up a little more.
