Sorry to hear of your strained ankle, at least a smoke will take the edge off
(any excuse to blaze one up)
Good to hear no fresh symptoms have appeared as those plants are very nice and it would be a real shame to lose any of em. I would also confer with your grow buddy to see if he has any advice as if he has planted his in similiar soil nearby he may have come across the same symptoms and may know of a remedy. I would also ask him how often he watered during your recent dry spell you had. Good luck.
Keep it green.
