You can check the Day 11 update bro. You specifically mentioned 3-5 litres, 10%-20% runoff. Imo, I never need more than 5 litres per 5 gallon fabric pot, even when top inch is dry. And I get significant run off. Heck I just watered today so I'm quite sure LOLThe FIRST time i watered was 2 days ago was not to runoff at all. Just a couple litres in each pot iirc so no runoff. Never ever watered this soil enough to get runoff until that final time and I only did it to 2.-3 pots. 3rd pot final reading was 1600ppm lol. They are actually 3 gals realistically as well. They have not drooped, infact the opposite, one of them is now full on praying and others following suit a bit.
Anyway, yes they wont need watering for about another week till they dry out and the pots are light to pick up.
Apparently super soil can have super high ppm runoffs and not effect the plants too badly. Hopefully they will grow out of it.
Like I said, let them be if they are healthy. The run off ppm doesn’t tell much. Especially if you take first few drops, ppm gonna high for sure. Think about it! You’ll get my meaning.
I have seen experts around here warn against mixing coco coir with soil. Weird things happen it seems but I have no first hand experience so gonna leave it at that.
If you have access to pre made soils, looks like you do and can afford it, why give up so soon? Like you said, you messed up the steps so it probably isn’t the soil’s fault. Mixing your own, you can mess up the same too. Just saying. At least run it proper once before deciding it’s not for you. I spent a long time reading and researching. Almost two years before I feel ready to go full organic living soil come next round.
If you mix your own, read up on all common living soil amendments and requirements. As many as you can. This includes inputs for macro, micro and minerals, together with bacteria, fungi, enzymes, hormones, amino, humid, fulvic acid sources. Get familiar with the bioavailability of all these inputs. Some are slow some are fast. Some are so slow it don’t make sense. Too fast too much and it burns or stunts. Understand how and why certain inputs are safer to add large amounts but why some, you shouldn’t? There will be lotsa contradictions online but follow logic and KIS!
Your setup is really nice. Pretty sure you’re not in my part of the woods cos I cannot economically procure the stuff you have. Hope my experience helps. Your thread title just gets my attention each time! Lol
