Good morning, fellow marijuana enthusiasts.
I have a plant — just one of 10 in the tent, that suddenly started developing these brown spots on random lower leaves. My thought is it's some kind of fungus. Has anyone seen it before?
The highest RH I see is around 58%, after the lights go out on a watering/feeding day. Temps go down to the mid-60s at night, and are in the high 70s, low 80s with lights on, with an RH of 46%.
Other stuff that I'm sure has nothing to do with it:
Organic-ish soil grow (soil was set up to be organic, but I'm using regular feedings of organic-based nutes to satisfy the nute demands under LEDs.)
soil pH: 6.3
End of 5th week of flower
No foliar sprays. The only pest this grow has been fungus gnats, whose population has dropped, drastically, after introducing some predatory mites.
I'm wondering if I should just take this plant out and give her the axe, before this shit spreads.
