The La Diva is probably just about to stop "vertical" growth.
And when I have early finishers,like La Diva, I will go ahead and start flower nutes with a bit of veg nutes through that last bit of growth before switching to full flower nutes.
I don't bother weighing small plants, but I got about 3/4 of a quart mason jar of dense nuggets from the La Diva. It has a very nice aroma, flavor, and high. I have seen a few larger phenos of it in grow journals.
If I see the strain continue to develop with the larger phenos, I would probably grow it again or if I needed something in 60 days it would be a good choice otherwise it is just too small for my tastes.
Once the La Diva is done get all your light on the Jack, it will reward you with a pretty good yield if you don't rush it.
