Excellent suggestions everyone, super appreciated. I trimmed the yellowing / severely banding leaves, had given it a lil bloom and calmag earlier + a splash of PH up - have some strips, will test runoff when I go to water tomorrow and see if I need to try and give it a little more ph up / make the last 2-3 weeks of it's life comfy so I get a little more fatness on these buds before we chop
