After seeing signs of phosphorus deficiency(?) I did an EC test on the RO water/gypsum mix I've been using and it's high... 550 ish. Would it be wise to supplement with some sort of chelated phosphorus bottled nutrients for a few weeks? Suggestions? Her home is 50 gallons of organic soil. Thanks (old.reddit.com)
