If you don't drain to waste in your coco anymore, what do you do?

I'm in the same boat as you. But now I'm torn between saucers and a single tray. I just can't seem to find a tray for a reasonable price so going the saucer route may be inevitable. I think I may go that same route. Get some saucers and modify them for drainage. I can't imagine going back to...

I've noticed a lot of growers are using coco with a drain to waste setup, and I’m curious about how everyone is handling drainage. Especially since coco needs to be fertigated multiple times a day during flower until a good amount of runoff. I tried the Floraflex drainage system but personally...

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...

You might have been right all along

I actually already learned this the hard way. So I usually don’t follow the manufacturer’s recommendations when it comes to light height and intensity, if I did, I’d likely end up with light burned plants right from the start. For example, take a look at the diagram they provided me below...

The lights are currently set between 400–600 PPFD, and I’m in week 7 to 8 of veg. I feel like that might be a bit on the lower side for this stage of growth, but I could be wrong.

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...

I tried hydro for a little bit, but I don’t think I’ll be going back to it. It just felt a little too messy for my liking. These days, I’m leaning more toward hands off, automated systems. I like to keep things as low-touch as possible, which led me to switch over to coco. I also experimented...

I actually ran into the same issue on a previous grow. I followed someone’s advice to let my medium dry back, and it ended up stunting my plants for weeks. Turns out, they didn’t realize I was growing in coco. I thought I was overwatering, but the plants were really just drying out. That whole...

I read that the bigger the fan leaf gets, the less efficient it becomes, and that at a certain point it's better to clip them so that lower shoots can get the light that the bigger fan leaf was robbing them of. Made sense, but then again I read a lot of stuff.

Unfortunately I already took off all of the fans that were showing symptoms, along with a few more. They needed some defoliation I thought. Below is what they looked like when I put them back under the light after the flush and defoliation. Further below are the other half that still have a hot...

After this situation, I plan on flushing every 2-3 weeks moving forward whether they're showing symptoms or not. Or maybe I'll just stick em with the BlueLab Pulse to monitor from time to time and just flush when needed. You live and you learn. Let's hope for the best

Below are some of the symptoms I've been experiencing, aside from the wilting of course.

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...

In the veg tent, I’m still using the older AC hardware, so I’m not able to track historical data the way you are. I do have the newer hardware ready—I just need to set it up and connect it to the network. I recently picked up a BlueLab Pulse and noticed the EC was reading as high as 2.0 at the...

I only use RO water

For reference, this is my other tent, in week 4 of flower. Running the same setup, Autopots with Coco medium. Even the same nutrient line.

Yea, I know that Coco is more like a hydroponic medium. It may have dried out a little bit before I switched to the auto pots. But ever since I've switched to the auto pots they have been drinking like crazy and staying moist.

I check ph every other day and it's always within range. 5.8 - 6.0
