I did try running a lighter nutrient solution at first, but I started seeing deficiencies. That’s when I came across Jack’s recommendation of 2.4 EC, and I saw others talking about pushing it to 3.0 or higher. I never went that far, but now I’m wondering if my average EC of around 2.0 might...

Hey everyone, I’ve been running into a bit of an issue with my 55-gallon reservoir, and I’m hoping someone here might have some insight. After a few days, I start noticing this dark brown sludge on the walls of the reservoir, and when I drain it, there’s a decent amount of dark brown flakes at...

I get it now and totally agree—I was definitely treating the coco like soil before. Appreciate the advice! Quick update: it’s been 3 days since I started heavily fertigating daily, multiple times a day, and honestly, my plants have never looked healthier. Thanks for steering me in the right...

Coco definitely loves its water. I got my fertigation setup to feed three times daily now and I still sometimes feed by hand in between, my plants have never looked happier. @MickFoster was a blessing for me, I don’t know if it was what he said or how he said it that resonated with me, but he...

This is coco

It’s only been about 24 hours, but with more frequent feedings, I can already see some improvement. Still a work in progress, but we’re getting there. Big thanks to everyone for the advice and sharing your knowledge!

Appreciate the info and the confidence boost. I’ll start feeding more often to keep the coco more saturated like you suggested. Also, thanks for the link—looks like I’ve got some reading to do. I’ll update this thread with how things go. Fingers crossed!

Just to clarify, when I say drain-to-waste, I mean that all my runoff gets pulled out with the FloraFlex drainage system and tossed. I know some folks collect and reuse their runoff, so I just wanted to clear that up About keeping the medium saturated and feeding twice a day, I’ve read a lot of...

I'd disagree that I'm treating it like soil. I have a drain to waste configuration setup and every time I feed, I feed until substantial runoff. I feed with nutrients every time I water and I don't water until the top of the medium isn't dark in color, which is at the moment every 2nd day...

After looking into it more, I think you guys are right—my coco perlite mix is probably too compacted and messing with drainage. I gave one of the fabric pots a little massage before feeding tonight to see if that helps in the next few days. If anyone’s got other tips or tricks, I’m all ears. I...

I fed them and then left for 3 days, I don’t believe that they recovered but I wasn’t here everyday to see. But, I doubt they would recover and then get back to the same point all within 3 days

I also noticed some weird tearing and deformities going on, not sure what that could be either. Maybe it’s related

So I’ve got 4 plants, all different strains, that I started from seed. I fed them like 3-4 days ago, and the 1-gallon fabric pots were feeling light, and the plants were looking a bit sad. I thought, ‘alright, let me give them a good soak, and they’ll bounce back and start praying again.’ But...

There’s so much contradicting information that I’m not sure what to listen to. I’ve read people say don’t go over 1.6EC, then others says they push close to 3.0EC.. I’ve read people say don’t go below 1.5g/g Epsom, then others say omit it all together.. I’ve seen people say don’t go below a PH...

Great answer

Can I ask which medium you use and which size pots, the EC in which you feed at and what your final PH you adjust to?

I usually always adjust my PH to 5.8 but all the research I’ve done says that calcium is best absorbed at 6 or a few points over.

I’m still kinda new to this, I had a few harvests a few years back but they were all in hydroponics, this is my first experience in coco. I did notice that I had some red stems and I also remember reading somewhere that it isn’t a good thing. Hopefully this could be another symptom that could...

if you don’t mind, I have a couple questions.. what size pots were you using, which medium and how frequent did you water/feed. Also what was the usually EC that you fed at?

My good friend, the kit I speak of is posted on their site and additionally on the Jack’s 321 feed chart. There is indeed a bloom bag of nutrients included in the Jack’s 321 kit. It is to be used for the first week after switching the light cycle to 12hrs for photoperiod plants to help induce...
