Ive got 2 GG Ive fed them all the same up to now a...

hey buddingbudda , yeah the two GGs are **almost** in the same conditions, and both are showing some issues on the leaves, that cupping is on both, but the one closest to the fan is more "burnt" than the others. Yep, that's wind burn my friend, you have that box fan pointing directly at them, not good ! simply moving the fan so it's not pointing directly at any of the plants will prevent the problem from spreading further. I had my box fan pointing directly at a wall in my grow room, that could work too. Another thing you can do if you have the $$ is to get a Diffuseair. The main idea is to have *indirect* airflow hitting the (future) canopy at an angle for the best results. but i just pointed my box fan at the wall. Hope this helps ! 🚀
