I never seen ro water with a ph higher than 6.1 in my life.....you might wanna calibrate the meter shake!

Maybe you could add a bit more info shake! Also. you running 50/50 perlite/vermiculite might also be causing problems....with not enough water retention! I never ran anything or seen anything saying 50/50 is a good mixture!
7.2 is the pH of the water before anything is done to it. i get it from one of those machines that dispense water at the grocery store and whatnot.

i might have ran my nutes at too low of a pH a couple of time as my meter was a little out of calibration, but since, i know it's calibrated to two points.

i adjust my nute mix to a ph of 6.0 or so, after they are added of course. i know hempys are a hydro system and should be treated as such. give your boy a little credit!

the 50/50 mix was just a starting point as i have read all kinds of ratios. killa you like the 4:1 (perl/verm) if i'm not mistaken. jrosek from IC and that thread you pointed me to likes 60/40 (perl/verm) if i'm not mistaken. so it was merely a starting point.

like is said, i dont' have to water them every two to three days. i can go a week or so between watering them. i've always just lifted them to see if they need water.

i have since recovered from the nute lockout/pH/molasses problems. the plants are looking totally healthy. i will get some new pics up tonight or tomorrow.

i do appreciate all the help and it sucks i can't get back to you guys sooner.

i'll be back later.
