Cannabis Fade
Fade, often called cannabis fade, refers to the natural color change in cannabis leaves as the plant reaches the end of its life cycle. During fade, leaves may turn yellow, purple, red, or orange as nutrients are reallocated and chlorophyll breaks down.
Fade is closely associated with senescence and late flowering.
What Causes Cannabis Fade?
Cannabis fade is caused by:
- Natural nutrient reallocation
- Chlorophyll breakdown
- Genetic expression
- Cooler temperatures in late flower
Fade is not automatically a sign of deficiency.
Fade and Autoflower Cannabis
Fade is very common in autoflowers because:
- Their life cycle is fixed
- Senescence happens quickly
- Leaf color changes can appear dramatic
Autoflower fade often occurs rapidly in the final weeks before harvest.
Fade vs Nutrient Deficiency
Fade is often mistaken for deficiencies, but there are key differences:
- Fade: Even color change late in flower
- Deficiency: Patterned damage earlier in growth
Timing and overall plant health help distinguish the two.
Fade and Harvest Timing
Fade often appears alongside:
- Bud swell
- Trichome maturation
- Reduced nutrient demand
Fade alone does not determine harvest readiness, but it supports other maturity signals.
Can Fade Be Controlled?
Growers can influence fade by:
- Genetics selection
- Environmental conditions
- Nutrient management
However, fade cannot be completely prevented in finishing plants.
Is Cannabis Fade a Good Sign?
Fade is generally:
- Normal and expected
- A sign of a plant finishing properly
- Not something that needs correction
Many growers associate strong fade with healthy harvests.
Quick Summary
- Fade is natural late-stage leaf color change
- Caused by senescence and chlorophyll breakdown
- Very common in autoflower cannabis
- Often confused with deficiencies
- Signals a plant nearing harvest
