Ahh, couple of u dont release that Canna Terra is a peat based soilless medium. Its not soil. (soil of cause people do a slurry test- waste of time i think).

Canna terra and Coco is essentially the same PH requirements and you PH the feed not the medium. As Rezza said you can test run off to see what the medium is holding but is only needed in extreme cases and if u feed to run off it shouldn't be needed unless u have major issues but its another tool in a growers arsenal to locate problems. Ive never tried it and ive heard it can be a rabbit hole, and as Oz says u can sit a PH meter in and watch the swings. Rigs used to do this as he was automated due to being a FiFo so he could see what was going on all the time with his cameras.

Not in coco Reza. Testing runoff is not an accurate way of detecting anything at all. Slurry test is the way to go. Coco runoff is useless to gauge anything at all.
It’s definitely bad advice because someone goes and tests their runoff and goes holy shit it’s way off then start trying to adjust things in the feed and the medium and create real problems for themselves.
it’s not going to tell you exactly what’s wrong with a pretty number on a screen. It’s used as an an indicator that something’s wrong. It can definitely tell me if the ph is off. If the ph is right the run off will be the same as the feed simple as that. Personally I haven’t tested run off in years (because I haven’t needed to) and I rarely test ph Now because my nutrient is stable enough that I don’t need to anymore (it comes out correct anyway).

I've never tested runoff in coco. Slurry testing is messy, and tbh i dont think it's accurate.

If you're noob to coco use quality coco like Canna and coco specific nutes. Ph 5.7-5.9 during veg, 6.0-6.2 during flower. I use Canna Coco AB, rhizo during veg, and pk during flower. Thats it.

Tap water is your friend. Dont use anything but 0.2-0.5 EC tap water unless you really know what you're doing.
Tap water can fuck shit quickly if you don’t know what’s in it. There isn’t a place in Australia that gets identical tap water, the mineral content changes from storage location to storage location. For example my water is pretty decent and isn’t considered hard or soft, drive 1/2 hour up the road and they’re pulling from a different dam and the waters so hard it’ll fuck dishwashers and washing machine pumps from the calcium carbonate buildup.

most people don’t really understand the ph scale Tbh. Like most people don’t realise that ph changes with temperature. Run off can be tested in any medium including coco to give an idea what’s going on In the medium. It’s not going to tell you the medium is sitting on ph of 8.2 but it’ll just tell you the ph is high

I saw this the other week and this guy knows his stuff from a few posts of his I read. Saves me from typing.

That’s why I never suggest the cheap ph meters. Good ones have temp & compensation.

temp compensation just adjusts the figure so it’s from the same temp range every time (probably 24 degeees c or something) it doesn’t stop the actual ph from being different but. What the meter will show and what’s actually happening will be different.

This is my 1st serious go I plant to have a killer set up but it will be probably 2nd maybe 3 run before I get a dehu
Killer setup without a dehu bro think about it. I got by without one but then yielded 6 more oz when I brought it and I lost 4 oz to rot before I woke up. $150 dehui made me more then 10 times that.
Give us a look at your grow mate
