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!
See the last 2 pictures of week 3 for reference. pH oscillating from 5.6-6.3 (currently at 6.3). Temps day/night @ 79/69. Following GH Flora Trio recommended ratios (but diluted down to 630 ppm). Raised to 800ppm today. Have not changed nutrient solution to date.
hey there, sorry to disagree with larimar, but this is clearly not light burn. Light burn doesnt yellow the leafs it bleaches them, the leafs dont yellow starting from the base and between the veins of the leafs . this is a magnesium related symptom. Just add more cal mag. Simple fix the problem will stop spreading pretty quick and the plant will recover. Hope this helps ! 🚀
To me it looks like atypical Lightburn ( you upped intesity=?)
the burns will remain,,, but if you lower the lightintensity,,, plants will grow nice leaves again. Young plants like this get totally clear with 50-75 watt of Light
those Quantumboards have an extreme high DLI output
I'm noticing a major difference between my two plants. They're both in the same reservoir with the same training and feeding. They're the same strain of Bruce Banner from ILGM. Is this much of a disparity typical? Could I do anything to minimize it in future grows?
I have similar problem. With me was LED light, on one side grow faster (maybe stretch more). Than I buy extra led light, now problem is gone. So maybe if you rotate light, every time you water plants
Harvest in 1 week? Close-up pics are of the most mature buds, but most buds are 2-3 weeks behind this. How do you handle discrepancy in maturity between plants? Between the uppermost buds and ones halfway up the cola? ILGM Bruce Banner grown hydro at F63 under 240w quantum board
+1 strain
