After adding nutrients.

I think you've overdosed on the Langbeinite... the way I use it when I grow in soil is to top dress once a month with 1 tablespoon of it - since it doesn't dissolve very easily, this gives a slow infusion of the 0-0-22... with the amounts you've given, you may be looking at a potassium toxicity. What I would suggest here is that you flush her - 3x the pot volume of pH'd water through each pot.... clear it all out and get back to ground zero.... When they dry out, give half strength nutes but don't even top dress with the langbeinite... save that for the next watering... and only top dress with 1 tablespoon... you can repeat that top dressing in a month.... but you can take your regular nutes back up to what you had been giving them after that first feed.... Good luck!
