Maybe get a soil test to see if the pH is way off, and you're actually know what's nutrient ratios are in your soil, rather than guessing. When you added the Dolomite to soil to fix the pH, maybe you added too much or too little?
Look like you are in pure soil, with only 1% perlite, that means they are prone to being too wet, and have poor aeration and drainage, so when you transplant.... transplant into something that's at least 30% chunky perlite, it's so much easier to fix problems when you have a good aeration and drainage.
Also, a bottle of inexpensive Earth Juice grow original will definitely not hurt living soil. It will only help. That way you're knowing for sure they're getting the nutrients they need rather than hoping. Good luck I'm sure they'll be fine :)
