I had an idea how to get calcium to the plants..... There is cricket feed that is for gut loading and calcium loading crickets to feed to geckos..... It looks like 1 mm tilapia feed but really colorful.... If you feed a little to the fish every few days would it help your plants have more calcium ?

and FYI the bush didn't die from any chemicals in the pee or anything but like anything that's alive that you regularly pee on it commuted suicide... LOL
