I notice after 2 weeks in an aero cloner that they start to get a white crust around the discs also seeing the same white residue around the lower stem where they enter the disc.
Is this Powdery Mildew? How to treat? H202? Bleach?
Thanks fore the quick reply that's what I assumed too with the salt....just wanted to double check and I clean them out with a good bleach scrub always.
