Nutrients in hydro celery
My question is about celery. I've grown it in the greenhouse but it takes a long time and with a late start this year I decided to try it hydroponically. I started from seed in Coir and moved it to ab ebb-and-flow system. It's amount eight inches tall now under large CFL's and doing fine but in one of my references celery is listed as needing Sodium and Chlorine in the nutrients. I'm using X Nutrients which have some Sodium but no Chlorine and I wondered about adding a little table salt. Anyone have any experience or thoughts?
