Well my guess is it’s pretty much the oldest leaf on your plant and that is why it yellowed on you! This is why we do defoliation! As your plant grows new leaves these big old leaves die out! 🍀👍 you got nothing to worry about! 💯🤟

Issues with leaves. Day 90 total, 30 of flower. Leaves have been getting more and more yellow the past week, with progressively more brown tips.Vpd has been pretty close to ideal, the pot had 1 gallon less soil so could be missing out on some nutrients? Possibly Potassium? Otherwise not sure what it could be. Does not appear to be N deficiency because the leaves are affected from the top too. What should I do to fix this
