Check ph. Research VPD as well to make sure temp/humidity is good

What are you feeding ? When was the last time you changed your reservoir? What is your PH and E? C? If it starts at the bottom, then that is a mobile mineral N P K Mg only . If there are necrotic lesions, then that’s potassium as that’s the only one with necrosis that starts at the bottom. At least necrosis right away as a first symptom. The easiest solution to anything is simply changing your Nutrient solution
