Curling from poor airflow and heat stress. Underwatering. Activated the autopot system finally, as the roots have had time to reach lower in the pots. Feeding microbes and microbe food (Purple Cow LiquiLife and BioActive).
This is my first home grow. More than 10 years ago I attempted a legacy grow, but it had to be destroyed before we made it to flowering. So this is technically my second grow attempt, but this will be my first time growing in a real tent and not a foil lined attic with a 1000W HPS light. Since December of 2023 I've been researching and prepping to begin this grow, researching the equipment, horticulture, biology, etc.
I'm using mostly AC Infinity equipment (tent, controllers, fans, humidifier, etc.) for environmental control, Spider Farmer for lighting solutions, and AutoPot Watering Systems for automated irrigation and soil aeration. I'm a software developer by trade, so I am trying to monitor and automate as much of my grow as possible. This way, I can track my actions and results over time and incrementally improve towards a consistently high-quality grow. And remove as much potential for human error as possible.
I plan to keep the best producer of this batch as a mother. Best producer in terms of who yields and washes the best into bubble hash.
I want to thank everyone in the Sticky Dojo (you know who you are) and the IL cannabis cultivator communities who have provided advice and support up to this point. Most everything else I know, I learned from Dr. Bruce Bugbee, Ed Rosenthal, and Greg Green and from resources provided for free by LibreText's Biology library.
