Sorry for replying so late.

I realized that MG was the wrong thing to use (especially the Moisture Control) because my plant starting getting worst and worst. It started like yours, some leaves getting yellow and eventually died off. This type of soil stays VERY moist and becomes quite soggy. What I tried to do to at first to prevent the permanent moisture of the bottom soil is to poke holes from the top with a thin screw driver. I gathered maybe the plants needed some oxygen. But this ended up not working; I kept getting new growth, but the plant continued to look sick.

The best advice I can give you is to go to my thread where I've encountered the same problem as you. Read it and you'll see what I did to get rid of the problem. The name is "Help me! My baby is drooping" or some gay name like that, I think I was high when I wrote that. :stoned:

But I am absolutely certain that a bad thing you got going is the big pots. The big pot will have bigger problems since the moisture at the bottom of the pot is very unlikely to dissipate. The big pots will also cause the plant to become root bound and at least for me this caused very very slow growth. You'll be amazed at what speed a healthy plant grows.

Now the plant is doing quite well and the new leaves have a very healthy green tone and growing speed.
