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

looking like a mild case of nut burn. hard to tell with the pics. try flushing and see if she looks better in a few days.

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)

No, I'm not using soil I'm using DWC. Dude told me it might be minor nute burn and to flush my reservoir. So I did and I'll see how their doing in a few days but yea looks like your girls had a case of it too.
