Hey what's up guys this my first grow and i had a couple questions. My plant is 4months old, 1 week into bloom or budding stage. I have had no problems till now. Some of the leaves the tips started to turn brown then white and crumble off also some of the center of the leaves started turning yellow but the ends are still green besides that plant looks healthy. It not all the leaves it like 4-7 out of the whole plant. Should I worry?
