If it's powdery/fine lime I think you'll find it filters down into the soil pretty easily during the first watering, and you'll see some cloudy runoff.

You are only watering once a week?

My thinking on it was that it would be better to transplant it into the correct ph sooner rather than leaving it in the way low ph for another week before watering it again. Like you, I've also heard all the stunting warnings and that you should always plant into your final container, but I think that may have been more valid for older varieties of autoflowers. Recently I've read more and more about transplanting autos without stunting issues so I'm not sure which path to take. I am a tinkerer and making up a new batch of proper ph soil will be useful in the future regardless so I'll probably end up transplanting, but I'll wait for more people to chime in. And if I do transplant it we can find out for ourselves if it stunts her!
So far I've only watered it when I planted it then again on day 7 after she broke ground.
it takes around a week for the lime to change the ph anyway it doesn't instantly change it over night so that would mean leaving it in its current pot for around a week with lime added which will gradually raise the ph or you can make a new batch of soil and wait for the ph to change all the while your plant is still in the pot with the low ph. so in my opinion i would leave it in the pot that its in and just add the lime to it. if you watered yesterday go and feel the weight of the pot just now and when you notice it getting lighter in weight then you can water again.
