zachstern, abort mission bro! You need to transplant into another soil or soiless medium that doesnt contain that type of nutrient charge. A slight nutrient charge in coco is common and with Fox Farms Ocean Forest soil it has plenty of amendments that contain lots of rich nutrients. I would spend my money on soil vs nutrients at this moment. Start simple, go get some Fox Farm soil Ocean Forest or Happy Frog will work, and maybe look at the Fox Farm nutes to use with the Fox Farm soil. The Fox Farm nutrients are more of a beginner line of nutrients so they will be easy enough to use. Keep things simple and stay away from anything that promises to feed you plants for extended periods of time. Miracle Grow, Shultz, Bayer, and other common garden fertilizers should not have a place in the cannabis growing industry but thats just my .02 worth. good luck to you my friend, take it for what it's worth...
