Okay, these plants are basically dying and I really don't know how to sort it. I've cleaned them out with water fully, and re-added the normal mix of Aqua Vega (NPK 6-3-8 for solution A and B) plus some Rhizotonic (0.6-0.2-0.6) and balanced it out with some PH up and down to 6.3ish pH. They should be moved into clay pebbles soon but before that I don't want them dying on me... Technically they're on a hydroponic diet, and maybe that's why, but for now they're in rockwall. They're indoors, under a 230watt CFL bulb.
