Help on cal diffcency

blood fish n bone... are you feeding a vicious animal or a beautiful plant? with a very low budget you can still get at least some good quality algae based tomato nutrients that would help your plant. fish blood and bones...will only attract nasty bacteria and bed smell plus...leave the fish alone use their excrements as fertilizer 😊 Plant might be too small to have a calcium problem. Make sure you water enough, every time you water, give as much to get some run off water in the bottom tray so your plant will not get nutrient lockdown and make you think it is a calcium problem
