Coco growing question

Quick question when growing in coco. Most people agree that it should be watered everyday to run off of around 15% and to keep it moist but not soaked. So how can you water everyday but not have it soaked? My pots atleast are definitely more than moist when I water everyday. Just scrogged today so thought I'd show

Reasonable except for the "not soaked" part; that's the whole idea; ideally multiple times per day.

You can feed 2-3 times a day-
As soon as it runs off there is approximately 20% oxygen in the coco. Don’t let the plant suck the runoff back in

Some things appear to be set in stone so I've just stfu about it, however it's up to you to take on board or not.

I don't have heat issues its normally cooler than ideal if anything, my humidity is 70%+ all year long.
Basically its extremely easy to avoid salt build up in that environment.

I've found 10/15% to be woefully short... 5ltr pots take around 1ltr 3x daily = 100/150ml per cycle.
Think about?
100/150ml from a 5ltr pot it's nothing, it's so little it takes 15 mins to appear at the bottom of the pot as a dribble that isn't enough to rinse anything, not in my tent at least.

In recent times to save wasting run off I've been getting my plants established in flower then of setting the ec, so if it's coming out say 0.4 too high I lower my nutrient ec to within 0.2, frequent run off ec checks are a must imo especially so around week 5/7.

10% of the pot volume daily would make more logic to me without of setting the ec that would be sufficient.

A lot depends on container and plant size. Mine right now is in a 2 gallon(more like 1 3/4), container. It gets autowater 6 times a day during lights on, and once during lights off. The problem is, it's a big plant, and it sucks the moisture out of the coco, too fast. I should've went with a bigger container.

I started with 2 gallon pots and I agree- I have settled into 3 gallon. As you said- you can’t fill it up to the rim so the effective size is smaller than listed. My plants want to fall over when late in flower so the bigger pots help keep them up. Bigger than 3 would allow the plants to get to big for my space.
Also large plants make a lot of humidity which gets hard to control. I use fabric pots and toss them after each use.

I was noticing burnt tips, and I know I was getting plenty of runoff, and I'm only feeding 1.2 ec, so it was a conundrum. At that time I was autowatering every 3 hours lights on, once lights off. I noticed the coco looked kinda dry, so I upped it to every 2 hours lights on, one lights off. It helped, but I still feel it could use more. Either bigger container, or smaller plant, next time lol

If you lower E.C. a little more once you go to multifeeds per day may stop your tip burn. I have started going to E.C. 1 once i am multifeeding per day. Once you are replenishing with nutrients and water several times per day it doesnt take a high E.C.

I've been told a long time ago on this forum to treat coco like hydro and that has worked out

What about freshly sprouted seedlings?

I would start in red cups /pick them up and feel the weight without any watering. And then would pick them up/feel the weight once watered[that would be helpful for me to tell diff between dry and wet]. My plants would stay in the cups until transfer them into final 5 gal bags
