ok, should i use ph'd RO water for flushing? or should I just use regular ph'd water?...I have a flushing solution too...it says to use 1-2 TSP per gallon so Im going to put in 1/4th of a TSP in every gallon.

Also i was giving them about 550 PPM so im going to cut it to 250 or so and work up tp 350 over the course of the week...but my question is this...

when I add cal mag to RO water it has ppm of about 200 per tsp
the Liquid Karma is generaally low in ppm ranging from 50-150
and the grow has the highest where half a tsp can range from 100-150

So should I use a the full tsp of cal mag always no matter what? then add the other to get to my ppm amount? or should i use less cal mag...say 1/2 tsp?


Also one thing i forgot to mention was I have a vortex 650 Cfm fan for exhaust(my room only needs about 350, i figure w/ charcoal filter and lengthy air ducting its about right)and i dont use a intake fan as the suction from exhaust is very good...and I have a fan blowing right under light & over plants plus one other fan for general movement in room
