ILGM Bruce Banner - Indoor DWC LED

Week 7: Plant 1 appears stunted compared to plant 2. #2 grew 4" taller this week, and #1 didn't grow at all. The root ball is noticeably smaller, as well. Additionally, the LST plant tie was too aggressive and one of its 8 main colas broke off. I attempted to tape it back together per instruction I found online, but it was completely broken off and beyond saving. Lesson learned for future grows not to train too aggressively, and to re-tie every day or two. The problem was that the plant continued to grow, but the tie was stationary, adding more strain on the branch which caused it to separate. Defoliated all of the oldest fan leaves on the lower nodes. Also removed 4 downward facing nodes on each plant (first nodes of first nodes on each plant). Moisture was beginning to collect, and the larger fan leaves were getting tangled with new growth and hogging the light. Adjusted nutrients and brought the pH back down. Also added more hydroguard. Raised lights and increased intensity to 20k lumens at the canopy. I'm going to switch to 12-12 light schedule today. I'm not sure what to do about #1's stunted growth. I've verified bubbles are coming equally out of air stones under both plants. They're obviously in the same nutrient bath under the same light in the same cabinet. It could be the stress from losing one of its colas, or maybe it's just genetics. Either way, I don't think there is anything I can do about it at this point. It's interesting with DWC to be able to isolate variables and see the difference between two plants with the same light/nutrient solution/training and watch them side by side. #2 is looking strong and healthy!
