I transplanted some clones into a new bubble system, and it's been awhile since I've grown. The clones were rooted well, and were in sponges that had been put in dirt to sell at the dispensary. I don't believe they had been in the dirt long, so there shouldn't have been much shock from rinsing the roots, but it's always a possibility.

I think the issue is the nutrient solution being too strong. I took out half of the solution and replaced with straight water to weaken the solution to about 40% of the recommended amount.
