Humic and Fulvic acids, I won’t bore you to death with their benifits.look it up if interested - I’ve used it , love it, never PH water.I use rain where possible, tap comes out at PH8.9 /140ppm ,I’m soil.
Peace
good man, if you are in soil, you dont need to waste your time with pH and you are also sequestering more of the carbon overhead to growing pot indoors than those of you in hydro, soil less and so on. If you grow outside under sunlight, this is clearly better still :-)
Very basically, nature balances pH by mixing communities of microbes. Fungus equals organic acids, equals lower pH, Bacteria equals bio films, equals alkaline and so equals higher pH. Higher the pH, more bacterially dominant your soil, media, water and so on is likely to be, and so the less access you will get to many of the nutrients you might need, esp if you aint in living soil.
In good quality soil we have approx 170 compound forms of P to access, in hydro you have the P2O5 you add and thats it.
You can avoid using P in soil and save money and the planets water quality.
In my experience, purpling is a habit of hybrids, not just in the Pot world but across loads of plant types, dont be fooled by marketing, purple plants dont equal P def plants with enough consistency to be called a character we can use as a guide to adjust our inputs.
To add, domestic N use outstrips agricultural use of the element every year, so honestly its no good carrying on thinking you are alone and making little difference as you pour.
this pot was grown indoors, using BOX, without pH and without added Phosphates.
