The ph-meter finally got shipped to my address. I am watering my plants from now on with water that has a ph between 6.0-6.5.
Royal Critical Automatic is growing really fast, Purple Queen Automatic and Royal Haze are also doing good. I think Fat Banana Automatic is doing beter the last few days, but she is the smallest plant.
The leaves of my Fat Banana aren't doing so great as u can see on the picture. Why is my plant doing this and what should I do about it to make it stop?
