How much, how often, and which Dyna-Gro formula are you feeding?
ALL plants need calcium on a regular basis, and I would think the D-G product could do that.

It happens when the growths are emerging, starting at the growth tip. It has happened on the 2 new growths and only starts once the groth is about 2-3 inches long. The rest of the plant looks healthy and its producing roots as normal. I use RO water (that I buy at the store) and flush each time before watering. I feed my plants weekly with 1.5mL DynaGro/1L water. This is the DynaGro

Really looks like necrosis and not a bacterial problem. I would have expected a bacterial issue to spread quickly. This has happened very slowly over the course of 2 months. I excised the effected leaf tips last night and treated with cinnamon. I just don't don't want to loose the next growth the plant makes. The rest of my plants seem fine but I'm worried they are effected too

I bought the CaliMagic supplement last night. Should I use it only on the one plant or my entire stock? Is there such a thing as excess Ca/Mg?
