Hello, I have some yellowing on one of my plants leaves and am not sure what it is she's deficient in. I am growing in 5 gallon fabric pots, in each one I used roots organic potting soil with about 1.25 lb of nature's living soil + 10 tbsp dolomite lime, 10 tbsp oyster shell flour, and 5 tbsp gypsum. I water using bottled spring water, the pH is just below 7 when I've tested it, about 6.8. Using ac infinity evo6 with the AI controller, so it tracks my temp and rh. Temp is around 70-75 degrees f, humidity is about 55-60%. The plant with the yellowing is my biggest plant, no signs of stunted growth. I am about 3 weeks into flower (from when I switched to 12/12). I am growing seeds from humboldt seed company, the plant in question is the big one in the back it is pineapple muffin, as is the front left plant. The other one is chicken n' wafflez (front right). I am using the self watering bases but still top water once a weekish. The yellowing has been going on since veg, added some bat guano during veg thinking it was a nitrogen issue. Doesn't seem to be exclusive to old or new growth. Did some lst to keep the canopy even, really digging these bud trainer bud clips. Anyway, I've looked at various charts and pictures of different deficiencies and can't seem to nail down which one it would be, thanks for any help!
