Coco, soiless, hydro, aero, fogponic need oh adjusting because they have next to no CEC (carion exchange capacity) unlike soil so they are mostly inert and do not effect ph much if at all.
 
That’s great! Sounds like an ideal scenerio too. I’m sure most people don’t need to PH, especially in soil but everyone has different water too. The NFTG line is a calcium based nutrient program, not Nitrogen based like most. I’m not a plant chemist so I can’t explain in detail…but apparently adjusting PH is critical for the best outcome with NFTG especially if your water is high Alkalinity and high PH (which mine is unfortunately). But if not PH’d after a while with the calcium carbonate build up from my water the soil PH will continue to rise and won’t allow proper chelation of certain nutrients.
ohhhh I see meow and you are totally right. I never heard of NFTG but sounds cool. Yeah my water here is alarming shitty for where I live. No joke my tap water is like 500-700tds and 7.5ph+ so that spooked me into gettin a cheap RO system for under the sink. Come to think of it the last sentence you wrote I think is exactly what happened to my Chem Cookies last grow. It caused my fabric pots to be white on the outside. I don't know but it was as if the roots would repel certain nutes like Cal and leech them out the pots
 
Who said PH adjusting removes alkalinity? My understanding is the PH will dictate if the calcium is able to chelate the magnesium in the medium. So that would be between 6.2-6.5 with nftg. If my soil is sitting at 6.9 or 7.2 , because of the calcium carbonate depositing in the soil over time, that would cause issues right?
No one said anything about pH adjusting removing alkalinity. What we're trying to get you to understand is the chemistry that is going on here. It's not as simple as add pH down to adjust because alkalinity will over time ... drive that pH right back up again. There's a difference between alkalinity of a water sample and its pH.

Your pots are far to young to have this buildup you speak of… it takes a significant amount of time and lack of runnoff to get a buildup.

available calcium can easily be washed from the media… i know you think it makes sense to you but you are greatly mistaken.

who said ph adjusting removes alkalinity? Well how you are describing it you are. How is ph adjusting nutrients going to adjust your soil PH? Its not… nor is it going to prevent a buildup of alkalinity which is why you are saying you should do it… eg it will somehow change the ph of the water in your soil.

im saying it wont and runoff is the key to prevent that If using synthetic nutrients

Exactly… lol ima leave the explanations to you. Honestly lost all my patience on this subject… its like beating your head against a brick wall

I never said or suggested that PH reduces calcium buildup. What I said was that the calcium buildup causes the soil PH to rise over time (sure, right now they are probably too young to see the effects of that, but preventative measures are best) and by watering at a lower PH can help stabilize the PH in the soil, combating the climb.

Right, it’ll drive it up over time…unless you keep it in check by lowering the PH of the water that’s going in so while it may continue to rise, it’s not rising as much.

I get it that at face value, what you're saying makes sense ... but in the realms of chemistry and how these things interact with each other things don't behave at a molecular level how you think they do.

Over time? How much time? 3-4 months? No, very highly unlikely no matter how much calcium is present in your water. The time-frame for measurable changes would be in a year or so of constant use. You're over-thinking this and in doing so you're at minimum making things harder than they need to be ... at maximum ... polluting your soil with excessive amounts phosphoric acid based pH down.

No you cant… thats the thing

Maybe that’s where the confusion is… I am not using any phosphoric acid or any other “PH down” product. The thing I would use to lower SOIL ph would be Gaia Mania which is a digested liquid form derived from soybean, feather, kelp, bone meals and worm castings. That is something that does bring the PH of the soil down.
 
Here’s a description of what it is…

Strange… I wonder if it was just full of water and trying to transpire.
 
@Dothraki

I'm going to circle back to the easiest answer to your water situation ... a simple one or two stage water filter system (not RO). Even a Brita water pitcher will remove enough sediment and minerals to remove all your concerns about your water.

where does it say this stuff does anything pH related?

1662490553572


I would run away from any organic brand telling you to pH your water before feeding as @MIGrampaUSA has already thoroughly explained in detail
 
@Dothraki are you following this feed schdule?

1662491223736


the tea they are talking about is the NTFG HH

seems like you're missing one of the key components to using NFTG?

Yes! I need to remember this. I’ll trudge it through this time…but plan to have a filter or RO system in place for the next one. Thanks for reminding me!

The Gaia Mania is used to lower PH for water only days. Seems to be what everyone uses and has positive results. I do use Herc Harvest when feeding, along with a few others. I actually haven’t had to feed yet since transplanting though. The soil had a little fertilizer in it.
 
Right, it’ll drive it up over time…unless you keep it in check by lowering the PH of the water that’s going in so while it may continue to rise, it’s not rising as much.
Are you using a peat based mix?
