Hey am desperately in need of some help. Noticed some brown spots appearing all over leaves on one of my ak-47 autos. It's affected leaves all over the plant and are dying couple days later. It keeps spreading. What is it? What can I do to save them? Btw indoor grow.
Maybe needs cal mag but I'm not too sure as I'm a new grower . My sprouts started to look like this and I fed cal mag and new growth got better but sorry I couldn't be any help. Someone on here will help gl with grow Sent from my iPhone using Grasscity Forum
