9/29/21 (day 52): I finally gave up on thinking the shortest plants would be able to catch up to the tallest ones, so I brought the shorter plants up off the ground to create a mostly even canopy across all plants. I also got some nutrient burn from the first feeding I did, even though it was only at half strength, so I'm going at quarter strength with nutrients from now on. The plant growth in super soil has been somewhat slower than I hoped, but I'm being patient and letting these girls take all the time they need to bulk up before switching to flower. Hoping to switch to 12/12 in the next couple weeks, at this point I'm only waiting for some more vertical growth now that the mainline/manifold structure is built.
