Your buds look great! 💪 I really like these bonsai-style plants. I'm not familiar with the strain, but the only thing that stands out to me is that the resin production seems a bit low. Have you checked your pH levels? Depending on the regional water quality, the soil's buffering capacity might not be enough, causing the pH to rise.
Additionally, you’ve skipped all the Biobizz products that provide more than the basic nutrients. 😅 If you haven't added any additional substances to your soil and are using a light mix, I strongly suspect that the issue is simply a nutrient deficiency. Given the plant's small size, you could have achieved better results with well-prepared soil from the start in terms of resin production.
With a few adjustments, you can boost your resin production and improve your overall yield.
