Flowering /feeding issiues

Hi, it looks like a strong nitrogen deficiency. Caused by a nutrient lockout. Definitely check the pH level in the soil. And flush the plant with water (pH: 6.9). In a few days, it will regain some color. However, the necrosis (spots) on the leaves will remain. Wishing you continued fun and success ✌️😉

Check if pods are not heavy might be too much water in pods and no air in roots. If your pods are light there is some nutrient deficiency. Can you give more detail what media you grow and what is your feeding?
