Issues making and using Als 5-1-1 mix: ingredients and nutrients

I've been silently lurking this forum for quite some time now looking for an appropriate substrate for my aroids. I dislike overly complicated mixes so I naturally more or less stumbled upon Taplas 5-1-1 mix.
I live in Germany and 2 of the 3 ingredients are sadly not available: partially composted pine bark and sphagnum peat (I also misread Als recipe and used sphagnum moss instead ...). At least I'm not able to find them.
So, I basically made the mistake of using uncomposted pine bark. I've been using the mix for about 4 months now, and most of my plants recently started showing signs of nutrient deficiencies (the pictures are just 3 examples):
There's no stunted growth or browning going on, only chlorosis.
Now, I have a few questions:
I know those questions are quite specific and understand that remote diagnosis is hardly possible with plant related issues, but I feel like I'm losing my mind about this. I really want this mix to work for me. I've been researching for days now, digging endlessly through weird, vague blog sites and forums. Maybe you guys have an idea.
Thank you for taking your time reading this.
