Your opinion please!

What do you think this is? Any idea? If you need more info about my setup let me know, Im running a DWC and have a 400 Watt MH about 14 inches away. There is a humidifier in the room, Ive read it might be caused by mist? Ideas?

Additionally, I have two plants in my setup and only one is suffering from this issue. This plant is close to the humidifier and it is the only variable I can pick out between the two that is different. All the bottom set of leaves have a brown/rust/dead look to them. All the top vegetation looks great. Heres some more pics of both plants. (Day 25 from seed)

any thoughts?

I don't think the humidifier would do that. How's your water ph? Have you checked under the leaves for bugs? It could need a shot of cal mag. Not sure on that one. Be patient some folks on here should be able to pinpoint the problem for you. They look pretty good though. Good luck!

Thanks man, appreciate the response. I didnt think the humidifier would do that, it was just the only thing I could identifify as being different between the two. They're both in the same water source, same amount of heat, same amount of light, same amount of wind, and the one thing different is the humidifier is way closer to that one. Its wierd that only select leaves are affected though. Makes me think deficiency. Problem is my ppms are around 400 and I doubt that they are def. I have given them 1/4 dose cal/mag and 1/4 dyna gro all purpose in tap water. Ph is kept from 5.8 to 6

Nothing to worry about dont change anything or you could fuck things up.
