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.
