Hey Growmie,
You're doing a solid job, especially this late in flower. Three weeks to go, and you've already put in serious effort with that 3-hour inspection, that’s how real growers win battles. Keep doing daily checks with a loupe or magnifying glass, focus on sugar leaf bases and crevices where aphids hide. A few can turn into a problem fast, so staying on them is key. Manual removal is still your best friend right now. Use a small brush, tweezers, or even a soft cloth to gently take off any you see. If one bud has a bad infestation, it’s safer to remove that section than risk contamination spreading. Avoid spraying anything oily or heavy at this stage. No neem, no Bioleat on buds. If you need to spray fan leaves, use a mild insecticidal soap diluted to about 0.5 to 1 percent, but only apply it with precision, and definitely not on or near flowers. Plain water mist and a cloth or cotton swab can help knock them off. Be gentle, don’t soak the buds, just enough to dislodge them. Aphids are soft and don’t hold on tightly if you disturb them consistently. If you have a controlled environment, consider releasing a small number of ladybugs or lacewing larvae. They’ll hunt aphids naturally, though they won’t completely wipe them out this late, it could still help. Maintain steady airflow and humidity levels between 40 and 50 percent. Good circulation keeps mold and pests in check. Make sure fans are circulating the canopy, not blasting directly at buds. If you’re still seeing aphids a few days before harvest, a post-harvest bud wash can help. Mix lemon juice and baking soda in the first bucket, then rinse in clean water. It’s a solid method to remove pests, dust, or honeydew if things get too close for comfort. You’re in the home stretch now. Keep it clean, stay on patrol, and finish strong.
