Is this nute burn, potash or Magnesium deficiency? (pics)

So before I get flamed, I've read the stickies. However this is my VERY FIRST grow, and I'd much rather be safe than sorry. it kind of looks like both Mg and Potassium to me...so I'm not really sure. Any help would be appreciated.

So...I was using GH flora series with lucas formula (in soil) and 100% strength and noticed yellowing tips on my plants. I asked around and YL420 told me I should use half strength for soil growth and I modified the solution.
I switched to half strength and just water every other feeding and things looked good until about 3 days ago, when this started to happen.....The plants are at day 35 of flower.
