Multiple auto strain run

They are done stretching this week. The Colorado cookies are definitely gonna be finishing first by the looks of it. The critical jack is showing some small deficiency on the upper leaves. Not sure why. There should be plenty of nutrients available in the soil. Possibly could be a pH issue but don't have a soil pen to test so I will just make sure to triple check the water pH every time before watering. Other than that, the ladies are looking great and hopefully continue as such till come harvest time which will probably be roughly 5 weeks away.
