ProMix... Is it considered hydroponics or soil gardening?

Ok so this might sound like a stupid question coming from someone thats been growing for over 15 years and has been using promix for about 12 of those years but when ph'ing water for use with promix, should you consider it hydro ph range or soil ph range.. I use AN sensi bloom thats supposed to keep "ph perfect" but its dropping my ph down to 4.3 and i totally overlooked it and lockout set in and i got some yellowing in my fan leaves, but i figured out quickly that my ph was to low but im wondering if I should ph it to around 6.5 (soil) or around 5.8-6.0 (hydro)? Ive been using promix for so long but never truly knew the answer to this question lol And i know this isnt really a "advanced" cultivation question but the growers that i want to hear from usually are the ones in this section.. thanks in advance

Promix contains little, if any NPK -- but it is buffered with lime which means it's got CA & MG.
Unlike coco, you don't need to worry about PH with promix.

If used out of the bag it is an "inert" media in which it has no real nutriotional values in itself.
It should be treated like hydro in rockwool or coco (coco usually requires a coco formula)

And watered with a hydroponics ph.


Now if you add orgainc ammendments then youd need to ask a soil guy if you would treat it a little like dirt.

Sorry im a hydro guy at the moment for about as long as you 15 years :)

Again, you don't have to worry about PH with promix because it's buffered with lime.
Hell I'm growing with promix right now and still haven't calibrated my new PH meter -- because I don't need it.

ive checked the ph of the promix after watering with nutes and its around 7.2 and i do have to ph my nutrient water or i get complete lockout. so im wondering since there isnt any nutritional value what to ph the water at.. Ive been ph'in the water to 6.5 but wondering if i should lower it a bit
And i ALWAYS have to supplement with calmag, if not id have a dead fan leaves withing 2 weeks of the start of blooming

thing is add a bit of sand and clay you have dirt, so.....
I use promix at my farm and only add pooh to it for my indoor, greenhouse and raised beds.
I water it when needed. I consider this dirt growing not hydroponics.
My hydro rock growing was much cleaner, wetter and lighter in all respects.

Ill agree with that

But i wouldnt put in the same category of soil just cause its brown and makes a mess :)

I ran promixe for about my first 2 grows

Never again i do not have patience for a media that dosnt soak up water readily lol
I loved coco but hated the mess

plus, lime, wetting agents, fungus, those make it not inert too.

if your promix didnt absorb water readily it was old, check the dates. I saw that on their website just a minute ago.
Mine is fresh truck delivered and dated. It sucks up water quickly and drains it out fast too. maybe old stock?

One of the downsides of peat is that it becomes hydrophobic after drying out.
I actually like Lambert HP better than ProMix.
It's chunkier w/less perlite.
