Week 3 and things are going along mostly smoothly.
B#3 started to show some deficiency: older leaves with yellow edges, new growth staying really light-green, and growing extremely stubby. To combat this, I gave 1/2 strength GHE Flora trio for the growth phase. This was fed to all plants, including the Jock Horror which helped it a bit.
B#4 has much more pointy and sharp leave fingers, maybe a different phenotype to the rest.
Going to top 3 of the plants in the coming week, and leave one as a test to see how differently they grow.
