It can already be observed that the substrate with the added coco coir absorbs water much better. I will give her as much water as possible.

So far, only a few leaves are affected. Since the substrate already contains 100 ml of dolomite lime—and as I do not wish to purchase a separate Cal/Mag supplement—I will water the plant once with 3 liters of pH-adjusted water (set to pH 6). This aims to reduce the nitrogen intake while relatively increasing the calcium intake provided by the tap water. The slightly acidic water should also help release more calcium and magnesium from the dolomite lime. CaMg(CO3)2 + 4 H+ - Ca2+ + Mg2+ + 2 H2O + 2 CO2 Furthermore, as the plant is already at the onset of the flowering stage—and should ideally be focusing its energy on bud development—I will remove the large lower leaves to prevent them from growing further and consuming calcium and magnesium that is needed for the flowers' development. Afterward, I will continue feeding with the same NPK fertilizer dosage. I hope this mild intervention will be sufficient to correct the issue.

Additionally, all the leaves have turned yellower. Consequently, I performed some calculations and determined that the Cal/Mag ratio in my tap water is unsuitable for the onset of the flowering stage—specifically, there is too much calcium. Therefore, it proved counterproductive to flush the plant and continue with a low fertilizer dosage in an attempt to avoid over-fertilization. The fertilizer I used—with an NPK profile of 7-3-5 + 1 MgO—would have actually supplied the plant with magnesium. All things considered, I probably should have applied a higher dose of fertilizer sooner—even if it meant risking slight over-fertilization—especially given that the leaves were turning yellow across the board, suggesting that the flushing and subsequent low fertilizer intake had actually triggered a general nutrient deficiency. Therefore, starting next week, I will resume a standard fertilizer regimen.

Its sister plant was also rather yellowish-green at first; it is possible that the strain generally requires a lot of nutrients. Some supercropping and defoliation were necessary because the branches were growing quite close together. This allows the lower flowers to get more light and air, which promotes their development and helps prevent mold.
