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.

Brown spots followed by necrosis on Mandarin Sunset.Any idea what could be causing this necrosis on my leaves? Starts with the spots and grows to crisp up the leaf. My soil should have plenty of calcium and magnesium. Happened once before on Gelato and never deciphered it.

Leaves curl, become crispy and have weird colors I need help. I've not had this problem before. The leaves get crispy and have weird colors. However, the buds continue to develop as usual. What could it be? Not all plants are affected. But it spreads slowly.
