I had to transplant this week as the initial pot wasn't doing it anymore. Unfortunately, the cardboard pot did not work as intended (it was supposed to break down) and worst, it made transplanting almost fatal for the plant. The soil would stick to the pot no matter what I did so everything sort of disintegrated when I cut the cardboard off. The plant was NOT happy, but thankfully, it did recover.
I was also way too slow at increasing dosage for nutrients and I saw some major color changes. I moved to week 2 of the feeding schedule at 100% strength. First feeding I went easy not to overwhelm the freshly transplanted plant (is that even a thing?) by pouring 50% of the previous schedule and 50% of the new schedule. On the last day of this week, I will feed it again with runoff.
After getting the transplant and nutes in properly, the plant really started getting better and growing fast again.
I did notice some color changes such as dark orange on the new growth followed by some light greens on the leaf veins. The orange patch seemed to recover on its own for now and the light green doesn't look too concerning. I'll see how it progress so I'll keep an eye on it.
