I'm looking for some help identifying the issue this plant is trying to show me. The organic bug has bitten me pretty hard and I'm obsessed with learning as much as I can. I'd love to hear any expert opinions out there, or even just educated guesses I've been using RO water for the whole entire run so I'm thinking Cal/Mg deficient? I'm also thinking it could be a K deficiency but the water has me thinking otherwise. I Think the issue may have been fixed in the last week because it does not seem to be getting any worse at this time. I top dressed with lots of different things over the last week so I'm not 100% sure what I did that may have helped or what it is I should be doing more of. Thanks for looking and I appreciate any input! P.S. I'm using regular tap water now.
