Im a noob but ill try help you out, Ive experienced nothing but problems lately growing soil and coco.
From problems i have experienced myself, you are either overwatering, have the begginings of a lockout from overfeeding or over rich medium, PH lockout.

Try flushing with plain water with 6.4 ph then feed them bloom nutes that contain higher potasium.Also add cal/mag at 1tsp.per gal.

I do add cal mg every watering, Didn't think about lockout I might have gone overboard on thr EW Castings by accident. Wish I could keep using overgrow during flowering

Frank, N defc. hits lowers first, and hard... N is readily mobile within the plant... this looks more like S defc. , maybe P starting too... EWC won't burn, that's not it at all, neither is overwatering,.... If you have feed only EWC, she's slipping into multiple defc.'s now, these are just the first to show... EWC is not a fertilizer, it's not a complete nutrient at all, but a nice supplement and very mild...
You need to get on some bloom nutes ASAP, and if you have epsoms (MgSO4), dose the soil with 1tsp/L to boost the S and Mg up..... S is immobile, meaning it can't be translocated from other tissues to new growth, that's why it hits uppers first and worst, but S defc. is atypical in that it a=can affect the whole plant's overall color, paling it out....
