Please could someone HELP!

Hello gardeners.

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.

Thanks.

  • Thanks,

    So maybe if I give them 23/6/10 until June time then reduce the Nitrogen and increase Phosphates and Potassium.

    I normally grow them in raised bed but this year I thought I would try something a bit different.
