Yah it's burn... drop the EC. .

thnx man i thought so just looked different yesterday

RO water doesn't do well in soil and especially with organics. Is your tap that bad, or did you just buy into the hype?

Any lime in the mix, or cal/mag for the RO?

Wet

damn wet i see you everywhwere its good your all over RIU helping people... im using coco i had ro hooked up to my house any ways so why not use it. people get mad at me though because after i pull a gallon or two there is no drinking water in the house no lime but i use calmag+ npk 2 0 0. at half dose seems to do the trick
