They sure don't need repotting yet.
I go by how long between waterings to decide when to repot. Once they need water within 48 hours of a good soak it's time. I let them get pretty dry so they are loose in the pots tehn just lift them out by the main stem, saw an inch off the bottom of the rootball and drop them into new pots filled up to the right height. I'll sprinkle a tsp of myco on the new soil and wet that down before dropping the plant in and filling the sides up then water everything real well so it's saturated.
Plants never miss a beat and I'm usually seeing roots coming out the drain holes within a few days. Never see anything resembling transplant shock and consider that a myth.
I'm off right now to repot 8 out of 13 so I can flip to flower in a couple days. Need them cropped and in the can before the end of Sept when I'll be running out to BC for a few weeks to visit family. Hoping to be catching some nice Coho in the Vedder on my 65th b-day in mid Oct. Time to start raking in those senior discounts!
