Dehumidifier water is maybe not a good idea for watering, this week I noticed some Black leaf tips and my best guess is something root related. I am back to using purified water with my Athena nutrient mix. Going to water less frequently and increase overall amount of water. Buds starting to weigh down the plants making it harder to water/move them around. Temperatures starting to drop with fall coming in which is great for my lung room/tent.
