I was stoked when I mixed a new gallon today, that when I added 2 ml's of liquid karma and my 1 ml of micro and grow, that the ph fell to a perfect 5.8. From what I have read, you really cant burn seedlings with this stuff, and I didnt have to use any of my ph down. Sounds almost too good to be true.
its been so long since i used LK that i dont remember if it bring down the PH at all i do know for a fact that Humboldt Nutrients Flavor-ful will bring down your PH. its just humic acid its some really good stuff, plants love any kind of fulvic or humic acid
everybody in coco should use that shit....everytime i expand my coco bricks i use 6.0 ph'd water with about 15ml liquid karma + 3ml calmag+.....your seedlings will thank you
