The reason for your wrinkled AR Leaves is a lack of Co2. It's typically with any plant. I've gone through this before with AR Mini. I suspect the DIY co2 isn't cutting it. It may also be the problem of your Staurogyne Repens, but I doubt it.
Twisted or wrinkled leaves can also be due to a calcium deficiency or too much potassium and or magnesium. If holes in the plant leaves start out as pin holes and slowly enlarge that is a sign of potassium deficiency.
I like to keep my phosphates around 5ppm and have found I have do just about triple my phosphate/potassium solution daily in order to maintain that level.
