Marijuana leave problem

A question from a fellow grower:

Can you help me with a leaf problem. I have read tons of articles but I almost have too much info for a beginner.

Perhaps over watering. If this issue is only on the bottom fan leaf, then you should be OK. Alow your pot to almost dry out before watering agian. Make sure the PH is between 6.5-7.0 for soil plants.
