Could this be boron deficiency? I thought I had dust mold a few weeks ago so I treated it with some vinegar water and took down the humidity bellow 20% I know my ph was good because it was always between 6.0 and 6.3
My humidity before the Brown spots appeared Was at 70 to 76% when I went down on it the mold went away but I got this afterwards around the same time I brought the humidity down but still not 100%
