Hydrogen Peroxide

worked well didnt hurt the plant and seemed to clear up any root issues

great!

Saved this particular plant actually from a overwatering i did, she wilted bad. And i gave her a sollution with water and this ( ph corrected ofc). And she was back up in just some hours! Changed over to pure zym as i think that is better for the plant. But still have 1 bottle of this saved away just in case:)
