Bought Macro Micro mix at planted aquarium. I knew it doesn't contain mono potassium phosphate as it doesn't mix with the trace element mix. My plants are showing signs of phosphate deficiency ex: dead patches and falling leaves off my staurogyne. So I'm going to pick up some phosphate, but not sure how much to dose for my tank. Also once I get the mix, should I make it into a liquid solution like I did for macro/micro mix or just dose dry? Anything is appreciated. Thank you.
