also tap water was used to flush them. tap water is ph 7.0, tds 170. have 80 gallon res. when mixing i follow directions but only mixed it for 60 gallons of water (but used 80).

i do have a fan blowing on them. lights are definately not too close. with the air cooled hoods i can put my hand right under the glass and its warm but not hot. hoods are cold. bulbs/ballasts/everything is brand new.

and these same clones were grown last summer outdoor great using 90% coco and 10% soil w/ metanaturals nutes.

also notices not all of the dead leaves (but some) have purplish stems. also a few of the plants are starting to get purple color in the stalks.
