Hello everyone. First and foremost, I appreciate any ones help and advice with this problem that I am having. As I said in my introduction I have had many questions answered on the pages of these forums so I am absolutely excited to finally call myself a member. Unfortunately I am in my first go at a DWC trial and am running into some issues here recently in my second week of flower. My plant is a Northern Lights Auto. I have been using Rock Nutrients and PHing the water around 5.8. I let the plant go into flower for about a week before switching to bloom nutrients. Last Monday I have them their first feeding of Bloom (1200ppm). 1 day before a change out the plants started showing some nasty signs that started to worry me. I realized that I hadn't checked my PH for two days because it was holding stable. The PH was low so I brought it back up to where I try to keep it. The plant went to sleep and when I checked on her first thing in the morning it had spread everywhere. It's mostly in the older growth, but I noticed today some newer growth at the top of the plant is showing signs of it spreading. I took a photo of it. It is a main fan leaf at the internode. One of the plants youngest though. From what I have read, I can't tell whether it is a phosphorus deficiency or rust mold. I didn't have an intake and feeling like the tent was getting kind of humid in the morning when I would open it up. My hygrometer wasn't showing a change in humidity though..lol. My roots look perfect. They have a little bit of hygroton stain on them but have had that the entire time. The roots are mostly a beautiful white even though my temps stay around 74-75. Anyhow, I know I keep going on and on, since I'm a little medicated I believe I'm all over the place. Lol. Just wanting to give as much info as possible in my seek for help. I look forward to hearing from you guys and really hope I can find some help before its to late. I am including photos on the rapid progression of whatever it is. The first one was yesterday. That was the second day after I noticed the issues and how rapidly it was progressing. The shots with the LEDs on and after were taken just before writing this post. She just woke up. Fresh mute change and flush last night. Doesn't seem to be stabilizing.

I was thinking it could be cal mag. The last two times I didn't add any extra in order to keep my ppms down. I figured Rock nutrients would put enough in thier line since the advertise just using thier 5 part system. Going to try adding some more cal mag. Thanks.
