Hey all. Wondering why the roots of my harvested plants didn't grow all the way to the edge of my 7 gallon smart pots. Plants came out fine and were sturdy during flower period but usually after I harvest and dump my pots the roots have grown all the way to the sides of my pots. This time when I checked the roots only grew about 2/3rds of the way to the sides of the pot as you can see in the photo. This is highly unusual. I only watered the root ball and about an inch or two outside the rootball the first few feedings in flower to force the roots to stretch out and look for water. But i still didn't get root growth all the way to the sides of the pot. Any ideas why this can happen? Does this mean I had unhealthy plants the entire grow? Plants looked healthy all the way to harvest. Thanks!
