Does anyone know what this could be and what I should do? I'm thinking Mg defiency? I'm using pretty crappy nutes the ph keeps rising and I have to keep putting ph down every few hours. Could this be the problem? CNS17 is what I'm using. I wouldn't recommend it. My plants are 4 weeks ppm 881

Are you using soil? If so, what are you using? I had the same thing happen to me and my plants. I was using Miracle Grow and my plants started to get the same brwon spots on a few fan leaves. I transplanted my plants last week, into some organic soil I bought at Wal-Mart for $5. They are doing a lot better now.

The first two pictures are from last week. The last two was taken one week later (yesterday)
