Killed all of them I guess I nutes them to death not sure the last just started drying out even when adding water no idea what happened they were healthy as he'll then dead leaves dropped burnt dried at ends then died I got a fan inside the grow tenting a tower fan with three fans sucking in air at the top so it had constant supply of fresh 17-20 degree air they were in large pots amazing soil so I guess it got over nutes and just couldn't recover. O well
