    New grower leaf problems

    Leaves are turning yellow around edges and tips. Ph is 6.1 ppm is 370 after nutrients added started with ppm of 21. Using foxfarm nutrients can't seem to figure out what to add to raise the ppm cause I'm pretty sure from what I've read it's nitrogen deficiency. Thanks for the help if you can.
