Please could someone HELP!
I'm in need of some help finding the N.P.K requirements for the Kelsae onion, I'm planning on growing some giant onions in hydroponics this year. I make my own hydroponic fertilizers and I can't find the optimal N.P.K requirements for onions on line. I'm thinking of making a solution of 23/6/10. But if anyone could help me find the precise requirements I would be very grateful.
