I have been trying to battle BBA and have been looking at my plants and I haven't been to worried about them because I have been busy. but know that I am not as busy I am starting to worry and they are getting worse. they are all yellow with dark veins and the aren't growing straight. And also they are rotting. I just need them to grow to battle the BBA and I need to know what deficiencies they have to know what ferts to by. recommendations on kinds of fertilizers are appreciated also. Thanks!
