9/30-10/6
10/4: Today, we are halfway through the third week of flower. Bud sites everywhere. Leaves look great. Environment on point. No issues.
The smaller plant has completely caught up and is now the larger plant by a little. The plants are sliiiiiightly different colors. It's not yet possible to tell if it's phenotypic variation or just different N levels in the medium. Curious to see how things turn out. The one other time I grew a Barney's Farm plant was the only other time I've grown two plants at once. They looked extremely different from one another. One looked like the pic on the package, and one didn't at all. One had the advertised terpene profile, one didn't.
pH upped to 6.1-6.2
I got really paranoid about the pot bases because people online were complaining that roots grew into the wicks and stopped water flow. So, I pulled off a delicate and difficult operation where I pulled out (one of) the bases and swapped in a clean one. In the second one I replaced the wick lines. Neither seemed to be particularly rooty. I think that's because I didn't use the bases through most of the veg stage when the roots are growing. Anyway, the bases are clean now.
One last thing: I put ArmorSi and CalMag in the reservoir of the "smaller" plant. In the other one, I only put ArmorSi. It seems like the branches are pretty flimsy, but it's still early in flower.
