@Delps8 It seems like you have a pretty solid understanding when it comes to lighting.. In my veg tent, I’m using a bit of an older setup with a light that runs solely on a Meanwell driver. It has two adjustment dials labeled “Lo” and “Vo.” Both seem to dim or brighten the light to some degree...

I went through the PDF you shared, and while I can’t say I fully grasp the technical details in the first part of your reply, I think I understand the general idea. It sounds like you're saying that calibrating my PPFD meter at 3000K vs. 3500K wouldn’t really make much of a difference, and that...

At this point, I’m starting to see that running Autopots with Jack’s 321 might not be the most ideal combination as is. If I do continue using this setup, I’m realizing that regular top-fed flushes and closer monitoring of root zone EC might be necessary to keep things in check. I’ve also been...

I’m noticing a new symptom showing up in the flower tent, and it started shortly after the flush. They’re currently in week 5 of flower. I decided to flush because the medium was reading between 3.0 and 4.4 EC, which seemed too high at this stage. I’m also starting to think it could be some sort...

Yeah, kind of, but just to clarify, there’s a wicking mat between the plants and that pool of water, so the plants aren’t actually sitting directly in water. It’s the capillary mat that sits in the water and draws the nutrients up to the roots. In theory, the plants should only absorb what they...

Right now, I’ve removed the capillary mat and have it soaking in a peroxide solution, so I’m just top-feeding for the time being. I’ll stick with that approach until things get sorted out. Once everything is back on track, I’ll reintroduce them to the AutoPot system and, hopefully, with...

I’m starting to think the issue may have been the light intensity all along. At first, the plants looked like they were recovering, but when I checked again a few hours later, they seemed to go right back to how they were, even though the EC was where it should be. That’s when I started...

You might have been right all along.

Just a quick update — it hasn’t even been 24 hours since the flush, and I’m already starting to see signs of recovery. It’s looking more and more like the high EC and salt buildup were causing a lockout. They’re definitely not fully bounced back yet, and I wasn’t planning to share any photos...

You might be on to something there.

I made the switch to Autopots about three weeks ago. The first two weeks went really well, but this past week is when issues started showing up. Looking back, I think I was running the EC too high. The plants weren’t absorbing everything, and the excess started building up in the root zone...

Just a quick update — I ended up taking about half the plants out of the veg tent to give them a proper flush. When I checked the EC at the root zone, it was way too high, so I flushed with pH’d RO water until the Bluelab Pulse showed it down around .5 EC. That part alone took several hours...

I check the PH of the reservoir every other day. I also check my pens calibration on a weekly basis and it's always on point. I'm always on top of the PH and the reservoir EC, one thing I never took into consideration is the salt build up. So, now I am starting to address that.

I did check all of that when I first set up the system, but I’ll go over everything again today once the lights come back on, just to make sure it’s all working properly. I didn’t add the two inches of hydroton at the bottom this time, but I actually still have some left over from when I used...
