32 days old Im manifolding…yknow learnin stuff. So Im trimming and I see one of my growth tips is black 1/4" leaves are twisted. the rest of the plant is beautiful barely a blemish on a leave. In my research I havent seen anything about mold in veg. I have an oscillating fan and directional fan in a 2x2x4 tent. I have good air circulation and I tend to move my pot around in its space. the next node in was dead and the next closer in was flourishing. I cut the funky part off. Can someone identify?

Looks like stem rot but not at the stem.

what causes it?

Ive found another…was touching the first one :worried: Help please…

To much moisture what are temps humidity, ph, are you feeding her

All that info is up there…I have been running high humidity…following VPD chart…experimenting …brought it down to 60%

Seems like you need more airflow in your grow area
