thanks for the input guys. the gals are responding well to the spike-up in ppm. my meter won't do different settings it gives one reading, considering all 3 elements(EC,ppm,CF) the girls are 5 wks into flower and responded well. i get a little confused w/ the inconsistency of my meter. i live near the coast and my water is hard-which i understand makes my EC high?? as the water sits out and somewhat evaporates i think my EC goes down while my ppm goes up. i am considering getting a seperate meter for each. my girls are happy and healthy-but always lookin to improve. i will post pics tonight when my cycle starts. thanks again!!!:thumbsup:
