Leaves turning yellow with brown spots and falling off

A question from a fellow grower:

“My plants are turning yellow with brown spots. Then the leaves will fall off. Starting to spread up my plant. Its LSD female plants from your company. They are in good dirt. They are on 12/12s for flowering.”

We need more info. Soil, nutrients, lights, watering schedule and etc etc. just because they think they have “good” soil doesn’t make it so.

Support please have them fill out a support ticket. Also encourage the grower to create an account and post in this thread
