Lol, I didn't know my personal journal was the topic of this thread.
I'm honored oh young one. But I think it should stay about water ppms.
Very kind of you to bring up my grow.
What's your tap water ppm?

What is the minimal ppm that is needed to prevent throwing the CEC of coco out of whack? That would be dream water to me.

I didn't know dream water was the topic of this thread either and here we are.
I read a lot of threads on here, your's is just another one. Especially when it's linked to other threads. I didn't go out in search of you. Don't feel too special.

If the question is directed at me, then no. I don't believe my TDS meter measures individual amounts of various compounds. The only good thing the TDS meter tells me is where i am with TDS. But I can use those readings, along with the amounts of other compounds described at the local water quality site, to get a half decent baseline of the nutrients I'm actually adding to the unknown water. Here's some other info on what our specific zone in the city has. Don't know if it's helpful for my needs, but it's at the least a measurement and not a total unknown.
| Total Hardness (mg/L as CaCO3) (2) | 170 | 170 | 169 | 177 | 182 | 190 | 182 |
| pH (pH) (3) | 7.7 | 7.7 | 7.7 | 7.7 | 7.7 | 7.7 | 7.7 |
| Temperature (°C) | -- | -- | -- | -- | -- | -- | -- |
| Total Chlorine Residual (mg/L) (4) | 1.95 | 1.93 | 1.93 | 1.96 | 1.98 | 1.93 | 1.92 |
| Alkalinity (mg/L as CaCO3) (5) | 121 | 121 | 119 | 125 | 130 | 136 | 133 |
| Conductivity (µS/cm) (6) | 350 | 349 | 353 | 363 | 383 | 385 | 378 |
| Caustic Soda (mg/L) (7) | 0.000 | 0.000 | 0.000 | 0.000 | 0.000 | 0.000 | 0.000 |

I mean, once you charge it. Shouldn't it stay good, haven't grown in coco for a long
A base line is good, plotting knowns is always a good KISS method.
You can buy specific solution that and even super simply test strips to further expand knowledge of what you are putting in your plants.
I personally am not one to worry to much over water unless I'm feeding heavy or running starts(or my water table is effed). Hell I've been highlighted a few times at running my seed and plug cubes to high... so theirs that

Just the posters content, " dream water " as a response to 67ppm, which really if the elemental analysis came back like common city water..is almost optimal for not needing to add to much other minors/majors

Yeah. I have a soil test kit but haven't used it on any indoor grows for some stupid reason. I use it for my lawn and outside garden occassianally when I see an issue. Prolly do more testing than just your average, everyday Gardener though.

maybe it’s the water that this is what’s wrong with him

Nope straight out of the 300 + foor well. Our water is very soft and very alkaline also.

Interesting. Ours isn't high in salinity, but we do have a softening system and that can replace the standard mineral hardness with salt. I'm just happy that we're super low on sulphur...which many wells around here are nasty with.

Yeah its weird we seem to have almost a natural softening system but sadly with the added detriment or high sodium. Luckily nothing else though

0.8 EC from the tap, i use it mixed with RO, quarter tap max.

325ppm from a 220ft well. It's pretty hard. 7.3ph Lots of calcium in there. I gotta take my shower head off every 6 months, and soak it in CLR. Been drinking it for 21 years.... no kidney stones so far! I keep them flushed with plenty of wine.
