Tap water analysis - ok to use?

[SouP_N]

Coco grow. What do you guys think? I want to get away from the RO water I’m currently using. It has just become too time consuming at the quantity’s I need to produce.

I'd have no issues using that water. Unless i'm missing something, everything looks excellent. I'd love to have tap water like that!

Appreciate that. I just defaulted to RO from the start and never really questioned it. Not using RO would take a huge amount of time/work off of me.

Follow up to this…

should I be shooting for the target ec on my feed schedule or should I add or subtract my starting tap waters ec (.3 ec) from my target?

It depends. A safe approach would be to feed 1/2 the recommended amount, see where your EC is and see how your plants react. If they look a little hungry, bump the EC up a notch. If the tips look like they're getting a little burned, pull the EC back a bit. All plants are a little bit different. You'll get the hang of it fairly quickly

Thanks. My target ec from when I was using RO water was 1250. I’m at about 1450 right now with my tap water and everyone looks happy so far. Switched from RO about 10 days ago.

Imo you need RO. 250ppm of chloride is to high.... Under 150 is usually ok Nd chloride is needed as a micro but that's to high.

Looking at the water report it's attached to the sulfur so this is likely a well or small town water supply? Not common to see in this in major cities.

Small town supply. You think this is detrimental or worth continuing this run on tap and see how it turns out. There is just no way I can keep up with my current RO setup.

Also are you looking at the correct column? I think that 250 number is the max allowance. 11.9mg/L is what was measured in 2020. Appreciate the help

Oh well my bad brother.... That's absolutely fine... May have some ph stability issues with that low alkalinity but that will depend on nutes. pH out ideally within 0.3 of input but lots can affect that

Thanks! Almost gave me a heart attack
Using GH flora + diamond nectar, armor si and cal mag. Thinking I can probably drop the cal mag. I do have to add a fair amount of ph down, but it seems to stay fairly stable once set.

Yeah your alkalinity will be fine... The armor SI is potassium silicate and even at half dose is enough alkalinity for RO water
