So, I'm gonna spray tonight with some Potassium Bicarbonate. Hopefully, that buys me some time. I already dropped the humidity to 40% and I'll be adding a few more fans.

I'm gonna pick up some actinovate and see how that plays out. Maybe all of these things with better cleaning practices will nip this in the bud!

It looks like/could be mildew. Not enough air circulation. The wall also blocks airflow. Perhaps also a pruning of lower growth would help. And removing the affected leaves.

I'm leaning toward Septoria at this point. I'm increasing the airflow for sure. That's been an issue. That run is due to be screened now, so that'll get all of the foliage nice and flat without it getting all on top of itself.

I don't think it's an aggressive fungal issue. Spores come in on the air all the time so cleaning probably wouldn't suppress this symptom. Especially during Autumn(fall) when the ground is covered in dead leaves being composted by the stuff. You could breathe in 10 Billion today.

Silicone is for cell wall strength isn't it? Everything I see here says drowning. If you have some hydrogen peroxide then slip some to a single plant and see if it picks it's leaves up.

I do a foliar rotation when of Mg, CalNit, Rhizo and AgSil til about day 23. I did have the humidity pretty high, too. ~65 til about day 35. I think conditions were ripe. Add to that water getting under my pond liner when my controller locked and ran my mister for 2 days straight! Room was empty thankfully.

Maybe the Si drench not foliar? I usually don't cuz I don't have to ph at all with my current setup, which is nice. I was gonna do a rhizo drench tonight and a peroxide one tomorrow to see what happens.

I don't think they're overwatered though. It's pretty hard to do in a hempy. They're still at a point where they need to be fed about every 2 days. Now that stretch is over, they're about ready to get fed every day. Plants are pretty big for a 2G pot. Hole is 2" up from the bottom so the res isn't super big.

Also, the bamboo stakes are a likely source for infection.



It is always best to avoid any cloth or wood in an indoor grow, even outdoors - wooden stakes, carpets, curtains, ropes, they're all sources for fungal growth.

Do you use Enzymes, should try may be a easy fix.

One bag of Fox Farm will fill two of those buckets maybe three or four with perlite. Depending on a few things somewhere around ten or twenty dollars each for grow media including organic nutrients and container for flowering. The way you are describing it may or may sound economical, leaf issues aren't what you want. I understand what you are saying, it's just so much easier Potassium bicarbonate Plant Therapy lime sulfur.

Good eye! I use them for my screens. Any thoughts as to what would be a good alternative?

Sadly, I also have exposed wood in the room, as well. I threw these rooms together in the most awful of ways. A carpenter, I am not!

No. I did order some actinovate, is that considered an enzyme? Since I'm in hempys, it's something I haven't researched yet.
