Just looking on a second opinion for my baby she seems to have tell tell signs of a phosphorus and potential nitrogen deficiency. Using BIOCANNA organic Flora and Rhizo Any advice would be help full right now! Shaded fan leaves turned purple where the light hit them.
It's hard to tell with the crazy purple lights, but I'm fairly certain that your fan leaves are expected to yellow and begin dying off in the final weeks of flowering, as the plant is effectively cannibalizing all remaining resources to focus on flowering and reproduction. I believe deficiencies look a bit more spotty and irregular when they occur. Those look like evenly yellowing leaves, which is expected from any flowering or fruiting plant as it enters old age.
I will take some here with a white led light . This is supposed to be a 10 week flower is 6 weeks not a bit early for yellowing? I understand it will feed off the leaves towards the end. Temps are consistent I count about 6 oddly purples and yellowing leaves.
