mcflowanswered grow question a year ago The decision to flush your cannabis plants depends on various factors, and the timing can vary based on your cultivation approach. Here are some considerations:
Natural Senescence:
Cannabis plants naturally go through senescence, where older leaves yellow and die off. This is a normal part of the plant's life cycle.
Flushing for Harvest:
Some growers flush their plants by stopping nutrient feedings and watering with plain water before harvest. The goal is to remove excess nutrients from the plant, enhancing the final taste and smoothness.
Observation:
If you observe that your plants are naturally yellowing as part of the senescence process, you might not need an extended flush. However, if the yellowing is due to nutrient issues, flushing could be beneficial.
Personal Preference:
Some growers prefer a more extended flush, starting a couple of weeks before harvest, while others may flush for a shorter period.
Individual Plant Needs:
If you have different plants with different nutrient needs or maturity levels (like Janis and Jimi), you can tailor your approach to each plant's specific requirements.
If you've been cutting off completely yellow leaves, it suggests that senescence is occurring, and you might not need an extended flush for those plants. However, for plants like Jimi that might need more time, you can adjust your flushing timeline accordingly.
In summary, flushing can be influenced by factors like plant health, nutrient buildup, and personal preference. Tailor your approach to each plant's specific needs and observe how they respond during the flushing process.
