I think this got missed up I took I need 1d1 to help delete from here... how did this happen

Im just sad we cant seem to teach the most basic concept of container gardening. The info we are given is standard for container gardening in the greenhouse food/flower production industry.
I first read it in the premier horticulture (pro mix) website and then saw it in greenhouse fertilization management guides. Its also on jacks classic website.
The standard is again. If you have 150 ppm water you are perfect and with proper fertilizing habits there should be no ph drop for months in buffered potting soil.
If you have over 250 ppm its time to consider mixing in ro water to achieve 150 ppm. Or have to add acid to neutralize the high calcium.
And yes they are just guidelines. Water content can change what is needed. Like mine has a bit too much iron. So i have to use a lot of runoff to keep it from building up.
Otherwise if you have acceptable water and you keep dropping ph it is from fertilizer buildup likely. Or worse adding uneeded ph down (acid) to get to an arbitrary ph # from an incorrect ph chart floating around on the internet. The actual solubility of elements is in a much wider range than the silly charts on the weed sites.
Then the grower adds lime. Or has already made these mistakes of salt buildup or too much acid introduced to the medium and adds it up front to mitigate bad container management habits.
None of this is my opinion folks. It is standard professional growing info.
And again. I have no agenda here. I am just explaining what happens. Grow any way you like and works for you.
But the constant help threads about ph and nutrients say it isnt working.
Only weed specific companies have instructed to adjust ph. The big companies and general ag never mention it.
Its really only on the bottles. So you use more weed specific products and keep going in circles. These companies knew weed growers didn't know anything about growing.
Its my thread so i thought i would try one more time.
:-) good growing everyone!
