However, there are some potential drawbacks to consider. While the mix promotes more blooms for more color, the water retention might be too high for plants that require drier conditions and could potentially lead to overwatering issues. Additionally, specific pH levels and the proportion of organic matter are not disclosed, which might be a concern for those needing precise control over their growing environment.
