Hey guys/girls im new around here but ive been having a problem with one of my girls outside. I have a 5 jack herer plants beginning to flower outside and ive noticed some problems on the leaves of one in the group. Theres black/brown patches on the new growth tips that i suspect is fungus? But im not sure. Also some brown spots on multiple leaves, abnormal growth. A few weeks ago aphids invaded my girls, ive been buying ladybugs and they have been working great ridding them. But what do you guys think is going on here with my leaves. I have pictures below. If you need more info let me know, i havent been able to find much info on the black/brown patches im noticing.
Black spots on the bud area of leafs I found this thread, and it seems like what we're experiencing is a phosphorous defficiency. Over watering may be a cause too, though. Sent from my SM-G930W8 using Grasscity Forum mobile app
