I suspect I have either leaf septoria or a calcium deficiency. I'm 2 weeks from harvest. The top leaves appear to be affected. The smell has changed (sharper). Not sure what to do from here. All advice appreciated :)

Plant #1 is showing some leaf discolouration. Not sure if it is nutrient burn/lockout or deficiency. I flushed her with R.O water just in case. Any ideas or suggestions? She's an odd one anyway, seems to be a different phenotype than her sisters.

Why are these leaves browning?What is the cause of the leaves browning on the shorter GG4 plants? They are closest to the fan but it’s pointed away and set to the lower setting. PPFD over those leaves ranges from 800-1100, while the ppfd over the unaffected Lime OG is 1300.
