Ratleanswered grow question 6d ago I see a lot of beginners taking the hard road to growing. It took me several grows to finally calm down and get basic and haven't changed since. I want buds not troubles. If your wanting to get fancy, find a sucessful grower on YouTube and do exactly what they do. If all the basics are good, PH feeding, water schedule, lights, humidity, temp, airflow and drai age then it looks like magnesium deficiency. Flower stage needs more magnesium and especially phosphorus for bud growth. The yellowing tips and margins and between the veins is a sure sign but thats only if her conditions are right. So many factors with proper growing conditions can cause stress. 10 weeks I to flower I'd be checking trichomes and harvest when 50-70% cloudy. You don't have much time left for recovery anyway. Good luck
