They look overwatered. The best way to tell if they need water is to pick up the container,and feel the weight. I have done a side by side comparison of MG moisture control and FFOF, and Roots organic, and FFHF, and the MG really, really sucks, comparatively. The other 3 were roughly the same, each with it's own characteristics. I think happy frog is best for the price, and has great drainage.
I'd transplant to a bigger container, water only when the plant needs it, and lay off the foliar spray. I'd try to find some better soil, too. You can buy a cheapo moisture meter from any gardening store, too. That may help when you are unsure of then to water. You'll get the hang of it after a short while. Good luck!
