If you can provide pictures in natural/white light it is always helpful for people to be able to diagnose problems.

I believe we are going to find after you give us some natural light pictures, that you are simply overwatering that one in the soil mix. The knuckle in the soil method does NOT work for growing weeds in a soil mix, which your coco/ffof is. You are most likely drowning your lower roots and when they shut down, it looks just like a deficiency. The other plants in pure coco are not having this problem, because coco likes being watered every day. So, it sounds like you are running those plants incorrectly too, letting the coco dry out.

Please read my How To Water article attached to my signature lines, after you snap those new pictures. I am pretty sure that the information contained there, will help you, at least with the one. Then for the pure coco plants, look up @Cultivator and see how he runs coco so you can adjust your watering method there too.

Please read the watering articles, both mine and Cultivator's... they are going to really open your eyes to a new way of doing this.
