MULTIPLE ISSUES. What is going on?n nute problems? Budrot?

Dear Yellah, I guess this is your first grow but your plant looks very bright, green and healthy. Your plant doesn't have any problem at all. Just keep doing the good job! Answers below in bullet points: - Leaves: It is okay for plant to loose some leaves or have brown spots at late flowering but it is also normal to drop some lower leaves any time of her growth. It is not a sign of anything unless it is all over the plant. - Brown Pistils: In most strains, they will turn brown and curl in and this is a sign that she is getting ready for harvest. Harvest window opens when 70-80% of those pistils turned brown. - Broken stem: The stem doesn't get enough nutrient to grow because of the damage she took. Try to tape and fix it and see if she grows. If not just cut the losses and your plant will channel this energy to other branches! No worries at al. Hope this helps, Cheers Y
