I am currently flowering my northern lights plant, I noticed it yellowing from the inward out kind of dramaticaly about 2 days ago and yesterday i nuted it for the second time (ever), and it looks kind of worse. The very middle leaves are small, thin, slightly brown, and almost completely yellow! Could you please help me? Thanks a lot!

wow if this happened right after the first time you gave her nutes, and that yellowing sounds like nute burn. I would give her straight water the next few times until she looks a little better, then I would start giving giving her half of the nutes you just gave her. If she starts coloring like that again, repeat the flush and half the nutes again. If you dont mind, whats the NPK on your nutes?
 
You can't go wrong with flushing. That sort of resets everything back to zero. From there you can proceed with caution. We have a great, comprehensive thread here on plant problems. It has great photo examples so you know what nitrogen deficiency looks like, or phosphorus, or potassium, or nute burn and all sorts of problems. I'm leaning towards either nute burn or nitrogen deficiency but you need to look at the thread and make that decision since you didn't post any pics. It's really hard to help anyone if they don't post pix of your plants.

I thought I did post a pic, that's strange. Anyway, thanks a lot for your answer, I'll flush her on the next watering and let you know if it helps! I'll check out that thread!

What's a NPK? Thanks for your answer!
