Thank you in advance for your help! I have been noticing white stuff on the outsides of my fabric pots. Im growing in Mother Earth coco perlite using suite leaf nutrients. Today is the beginning of week 10 from sprout. All are different Autoflowering strains. I previously got help from you guys with my plants all suffering ph issues. That seems to have been fixed mostly. Although I am having Fox tailing. Anyways I have been noticing white stuff on the surface of coco and outside of fabric pots. At first I thought it was salt residue or maybe some sort of beneficial bacteria because roots pop out of pots too. Now wondering if it is actually pm?
