Early in the week she had nutritional problems so I raised the lights and started feeding her daily. Leaves are dropping a bit but her color looks really good.
Update: appears humidity levels too low, too much airflow. I opened the tent and turned off the exhaust, the exhaust wasnโt moving hot air fast enough even though the side vents were open. All this airflow and heat caused low humidity. I reduced watering to ever other day just in case the roots were too wet. Afghan likes a dryer condition even though I am using coco/perlite mix it seemed too wet for these young roots.
