Much better with less langbeinite, just an fyi, you will probably still test too high for K, but it probably won't be a problem. It's a good idea to test your soil just so you know what might be too high (so you can watch for lockouts) or what might be too low. Coots type mixes almost always test too high for K and low in micronutrients. I checked your list and are you using oyster flour or something else to buffer the soil? My experience is that living soils (that we make ourselves, not like in our backyards lol) tend to acidify quite fast due to the heavy bacterial action. This tends not to matter if you have a big enough mass of it, but in smaller pots it can be a problem. Also, one thing to remember is that these Coots type mixes tend to lack micronutrients-pretty much all of them. So I would dose it a couple of times with any good micronutrient pack, or something like Bio Ag TM-7. You want to give it to them a couple of weeks before you flip to 12/12 and then a week after. Micronutrient deficiencies tend to rear their heads during a good stretch. Good luck! These living soils are fun but if you have problems with a new mix (usually starting in stretch) it's very hard to chase the problem down-on the other hand, if you get lucky with your mix, you'll have it for quite some time, and they make really tasty buds.
