I just realized that the "1 Gallon Nursery Pot" that I have been using as a measuring container is not actually 1 Gallon, as in 3.785L (1 Liquid US Gallon) But much less at 2.5L I measured 10X 250m measuring cups to fill it. Maybe 11. This is without major compaction, just light compact enough that there are no air pockets.
I did a quick search and it seems this is standard with Amazon
"NOTE: 1 gallon of loose soil will fit in this pot when compacted. Actual liquid volume is 2.9 quarts"
"These pots actually hold 0.664 gallons and not 1 full gallon"
So all those mix recipes, did they use 1G nursery pots or an actual US Liquid Gallon Container at 3.787L.
Im assuming 3.785L Measuring container, which means that
I have been making my mixes 26% too strong!!!!!!
and yes the plants arent happy, else I wouldn't be worried about something like this.
