RJS CalMag Paph-MX-6.0..Goood, Bad, or DEADLY?

[RJSquirrel]

no measure EC....have to borrow a meter for that or do the math on all the ingredients...


This is a monthly mix..it gets 2 irrigation waterings in between. Should be no build up of salts in the substrate. The PH of the water mix only makes the nutrients available to the plant, it doesn't live in a 6.0 state. Now I need to test the bark mix to actually see what it is, as low PH soil is bad indeed. Rainwater here is 5.5 to 6.0 so Im making my tap water PH more like rainwater. Ever wonder why plants seem to do better after a rain? Its because the PH makes the micro/macro nutrients more available in different ranges.

This is getting complicated real fast but the lime leeching thru should raise the PH of the soil back up after the plant has picked out what it needs..I sure wish a few experts would help me out ....I'm kind of out on a LIMB dangling



hmmm now Im reading "hardness is actually a measure of calcium and magnesium in the water bec it is insoluble salts of ions"...I don't have to do any of this it looks like..I really wantto make a secret sauce for paphs

" * Macronutrients tend to be less available in soils with low pH.
* Micronutrients tend to be less available in soils with high pH.

Lime can be added to the soil to make it less sour (acid) and also supplies calcium and magnesium for plants to use. Lime also raises the pH to the desired range of 6.0 to 6.5.

In this pH range, nutrients are more readily available to plants, and microbial populations in the soil increase. Microbes convert nitrogen and sulfur to forms that plants can use. Lime also enhances the physical properties of the soil that promote water and air movement."
