K Deficient? 1st time organic grow.

Well, I mixed up some super soil a while back and everything has been going well untill my best looking space bomb started to look like it was wilting a bit, looked closer and noticed a small deficiency. It's been a couple days since and my space bomb isn't looking too happy. The other strain, Tahoe OG, is thriving right next to it so I don't really see what I would've done wrong. Looks like a potassium deficiency to me. The only thing I could think that I did wrong was adding too much azomite. Is it too much calcium blocking out K? Maybe not enough dolomite lime to balance the ph? Then again I was told to throw away my ph pen now that I'm in soil. Please help me get my facts straight.

here's some pics

Yep, if you can, give something with Ca, Mg, and P and K.
You still got plenty of N.

Subs soil is loaded with nutes though. Oh well I'm just going to keep watering them and let nature take its course.
