These girls are growing nicely but the center girl looks a lot healthier with more vegetation. I changed my temperatures for both day and night. Night time I'm trying to hit mid 60s to increase stretching with a higher
DIF and day time to hit mid to low 80s to promote higher leaf temperatures because LEDs run a lot cooler. This will help growth by enabling the leaves to function better in a wider range of VPD (Vapor Pressure Deficit).
