Pistils turning dark

It is completely understandable to feel concerned when you see changes you weren't expecting, especially during an autoflower run where the clock feels like it’s constantly ticking. However, seeing orange hairs at day 47 is very common and does not necessarily mean your buds will stop growing or that your harvest will be stunted. Here is the breakdown of why this is likely happening and why you shouldn't worry about your yield just yet: 1. It’s a Normal Cycle, Not a "Finish Line" Cannabis plants don't turn all their stigmas (hairs) orange at once. They often go through "waves" of growth:  The "Wave" Effect: Your plant will grow a set of buds, and you'll see fresh white stigmas. Those will eventually darken as the flower matures. Then, the plant will push out a fresh batch of white stigmas, and the process repeats. This "rinse and repeat" cycle is what builds the density and size of your buds.  Day 47 Context: Depending on your specific strain, you are likely in the middle of a heavy "bulking" phase. The plant is still actively building biomass, even if some of the older, lower, or more exposed hairs have turned orange. 2. Environmental Factors Can "Fake" Maturity Sometimes, stigmas turn orange prematurely due to environmental factors rather than genetic maturity. If these factors are present, it’s just cosmetic—the bud itself is still growing fine: Airflow/Wind Burn: If you have fans blowing directly on your buds, the constant movement can cause the delicate stigmas to dry out and brown/orange prematurely.  Light/Heat Stress: If the buds closest to your light are showing the most orange hairs, your lights might be slightly too close or the temperature at the top of the canopy might be a bit high. Physical Contact: If you’ve been handling the buds or if leaves have been brushing against them, that can also cause the hairs to darken early. 3. Why It Doesn't Mean "Small Buds" The size of your buds is dictated by the plant's health, nutrient uptake, and light intensity, not by the color of the stigmas. As long as your plant is still producing new white hairs (even if they are mixed in with older orange ones) and you don't see signs of major stress (like yellowing leaves, heat-stressed tips, or pests), your plant is still focused on production. How to Stay on Track Ignore the Hairs for Now: Use the stigma color only as a very loose "progress bar." If you're seeing mostly white hairs, you're definitely not ready. If you're seeing a mix, you're likely right in the middle of development. Focus on Trichomes: The "Gold Standard" for harvest is still the trichomes on the calyxes (the actual pod the flower grows from). At day 47, your trichomes are likely still clear or starting to go cloudy. Don't worry about the harvest date until you see those trichomes turning milky white.  Check for Pollination: Just to be 100% sure, take a close look at the base of those buds where the orange hairs are appearing. As long as you don't see small, banana-shaped structures ("nanners") or round seed pods forming, you haven't been pollinated.
