I added mycorrhiza to the coco coir from a local store. It turned out that there is slow release fertilizers in it. Was not indicated on the packaging.Please Help! First time after watering with 5.7pH 400ppm drainage water was 6.7pH and 800ppm. I flushed her to 400ppm. Yesterday was the second watering (450ppm, 5.7pH) and drain was 700ppm 6.7pH. I flushed her to 460ppm (1.5l of water), but pH still 6.6 How to fix it?

whats wrong with the leaves?Im sure this is nothing to worry about but i just want to know what it is. Is it genetics or is it a deficiency that i can sort out. Im only feeding water at the moment. Also is there a name to refer to this condition? Because its not twisted or wilting?
