Help diagnosing my strawberry cough

Maybe more cal/mag?

Now, just the one branch has something going on and I'm not sure what exactly. Heavy handed with the fertilizer? She's indoor and that's the only thing I can think of since everything else stays pretty constant. ~10° variation in temp at any given time, 10-25% on the humidity. Figures once the other two finally got comfortable enough to grow, Ms. IDGAF gets sick.

Flushed her last night. Removed damaged leaves. If she doesn't drown we may be OK. Figures since my two problem children are now happy and growing more like weed

Post flush, put her in a 10 gallon, don't think I caught it in time, but we'll see. Stalk is still green, but not a single leaf not affected/damaged.

A moment of silence please.
