Mandarine Jam (Sensi Seeds)

OG_Big_Worm The week begun a little worse than the week before, as the Mandarine decided to stretch massively, resulting in tip over, which I resolved by putting more substrate on top. Besides that, everything was going good so far.

OG_Big_Worm This week brought pretty much new growth :). Decided to top the plant and it turned out to be a good decision as she continued growing as happy as before.

OG_Big_Worm As she was still in recovery from the first topping, there was not much I could do :). Growth continued as before - but still not enough in order to top again.

OG_Big_Worm Did some HST/LST this week. Heatwave in Germany caused super high temps in the tent, fortunately this is only veggie right now, so I am not too worried, trying to maintain perfect airflow and appropriate VPD.

OG_Big_Worm This week I did some more defoliation and removed all the LST/HST-Clips from the plant. Plant is looking good so far, but she still needs a bigger stretch before I top again, also she needs to stretch in general as I want her a little bigger before I send her into flowering. So for now it looks like one more month of Vegetation 😢 But nonetheless I am pretty happy with the plant so far and today her 3 little sisters popped so stay tuned on my other Journal 😁!

OG_Big_Worm This week was a heavy training week. Yesterday I topped around 20–25 active tips and combined it with strong LST/HST to spread the canopy into the SCROG net. A few branches audibly cracked during bending but remained connected. The video shows her current condition after yesterday’s topping and HST bending. Right after training she looked stressed and droopy, while she is now standing up again and pushing healthy new growth. I’ll give her time to recover before any further work and wait for roughly 2–3 new nodes on the fresh shoots before deciding when to flip.

OG_Big_Worm Troubleshooting & Recovery 🌱 This week was mainly about recovery and troubleshooting after last week’s heavy training. I noticed that the leaves were staying lighter green and weren’t “praying” like they used to. A few pale/white spots also appeared, while the substrate stayed moist for quite a long time. I finally started checking pH and EC properly. My tap water is around pH 7.8, and my usual mix with 2 ml/L Bio-Grow was still around pH 7.1. This may have affected nutrient availability. For the next feeding I added Bio-Grow, Root-Juice, Bio-Heaven, Acti-Vera and CalMag and adjusted the final pH to around 6.2–6.5. The good news: there is fresh growth everywhere and all the previously topped areas are developing new shoots. Now it’s time to leave her alone, improve the wet/dry cycle and see how she responds. 🌱

OG_Big_Worm After the heavy topping and HST, she has visibly recovered. The shoots have straightened up again, and the crown is becoming denser and more even. Some leaves still show a bit of stress, but overall the new growth looks healthy, and the plant is filling the available space well again. This week, I mainly gave her time to regenerate and continued to observe the structure.

OG_Big_Worm On September 9th, I switched to a 12/12 light schedule, marking the start of flowering. Mandarine Jam continued to spread out this week and is developing many active tops. The training structure is clearly visible, and the canopy is becoming denser. Some older leaves show lighter coloring and rust-colored spots, while the younger shoots continue to grow. I am keeping a close eye on these discolorations but otherwise letting the plant continue undisturbed.

OG_Big_Worm The transition into flowering is now clearly visible. Fresh pistils are appearing at many tops, and the plant is carrying a dense, fairly even canopy. After the intensive training, she remains compact and bushy, with numerous small flower sites distributed across the entire crown. A few lighter leaves are still present, but overall growth and flower development look stable.

OG_Big_Worm Flower development is progressing nicely and the canopy remains dense and fairly even. The stretch has slowed down, while the individual bud sites are becoming more defined and starting to build visible clusters of fresh pistils. Some older leaves still show lighter areas and minor discoloration, but overall growth looks stable and the plant continues to respond well to the flowering conditions.
