I need a little help from my friends...

Plants are starving. Visible N, P and K deficiencies. Hit with gypsum and a bloom booster high in P.

Learn to fertilize correctly!! None of that packaged crap gets it right.

Speaking of learning how to feed properly. Just the person I wanted to talk to.

I've followed a few of your threads and I recall where you were talking about balancing. Got me to thinking and to finally see what my numbers are like. I'm getting some advice from Bill Farthing in a thread of his and I'm starting to learn.

I've been running Jacks 321 at 2.0EC and this run in particular I started boosting Ca by 60ppm a week prior to 12/12 and I'm still at that level. Other runs, and prior to now, I've maxed out at 1.5EC

I have biomin calcium now and was gonna order some haifa mkp 0-52-34 for pk. Thoughts?

I'd really, really appreciate any guidance. I've been struggling for a few years now trying to dial things in. I'm finally at a point where most of the fires are out and a system is developing. If you wouldn't mind PMing, I'd love to hear your thoughts.

Thanks!!

Plastic or steel stakes would be an alternative. Or nylon netting.

Wood panels and ceilings can be treated by chalking the walls. Chalk is also anti-bacterial.

Thanks for the tip! As each room comes down, I'll be making some major changes.

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!

I would suspect too much water based on the leaf tip and leaf edge necrotic tissue. It’s possible to only find it on one section of the plant and no where else.

Could be too much water in one area of roots and nowhere else or could be the beginning of spreading issue.
I’ve seen it with cannabis and other plants, how a partially damaged root system will have a corresponding damaged above ground issue.
Common example would be tree roots pruned for a sidewalk or driveway, that cause branch loss months later. Doesn’t alway happen but not uncommon.
65% humidity is not high, with a 72-74 degree temp is about ideal VPD to shoot for.
I like SIP/ hempy’s in theory, and have run some that kicked ass for a few months, but eventually had issues. They were a new design to be fair and likely were media based problems versus problems with the actual practice/ design.

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.

Going that route would not only break the bank but require a full relearn on everything. 3 rooms running perpetual with perlite hempys using Jacks 321. I agree in principle, though!

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

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

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.

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.

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.

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!
