That looks like an Mg deficiency. Defianetly not pest related. It almost looks stunted or rootbound as well. How big is your pot. If u dont have it in a big enough pot, try transplanting to a bigger pot and then flushing it.
That is NOT an Mg deficiency.
First, I suspect you have insufficient light.
Next, we need to know pot size relative to plant size, how long it has resided in the pot, and the soil type.
Information on the pH of your soil runoff is also important.
I see evidence of a potassium def/lockout, but WHERE it's coming from needs to be determined before we can tell you how to solve it. My guess is if the plant has been sitting in the same pot too long your soil chemistry is off... filll out Stitch's troubleshooting form and we'll get it sorted.

Huge problem: You have added no lime to counteract the acidity of your peat! Hence the low runoff. The only thing saving you is your hard water. Had your water been soft, I'd expect to see runoff numbers even lower!
Let your soil dry out slightly between waterings- constantly moist soil makes plants react more severely to acid soil problems.
Flsuh with water at pH 7 to bring your runoff up to about pH 6.7 (it will drop again, promise
) and constantly monitor your runoff. You will be wanting to mix up your fert solution and then adjust it to about pH 7 before giving it to your plants, again to balance the acid soil.
Next time... don't forget your lime!

My hunch would be that she's feeding heavier and thus showing deficiencies earlier than her less ravenous counterparts... try to fix it before they start looking peaked too!
Well, I'll bet it doesn't stay in those limits long.... Yes, what you have there could very well be a Ca deficiency or lockout. Neither Epsom salts nor molasses contain calcium. You'll want to be running calmag, pHing your fert solution to the high end of your desired range, and definitely watch that runoff pH for signs that your soil is going sour on ya.
