I suspect that if you spent the money getting and useing a UC system you already know how to grow. So you will probably want specific coco info. There are a lot of people that can help on here. I can answer some of your questions/concerns as well.
"before it's too late"
How far along in this grow are you?
are you subject to a specific number of plants under your MMJ states laws?
What is your EC level? coco seems to like to hold onto salts and build up.
I am about 2 weeks right out of the cloner, yes i am subject to MMJ laws, we are allowed 12veg/12flower for every card in the household unless you have additional caregiver cards which i do, i run 24 in the coco room, (12 mine-12 my girlfriends), and i have a UC room with 16, 13 gals, and a UC tent with 8, 8 gals, and i have a mother/veg room with 8 plants, i technically can have more plants but im not really sure because of the very very grey laws round here, my ppm are @ 650, my mix is all orgainic and i run it very high though, have ran it in the UC at 2250 ppm on the 700 scale durring flower, 1650 during veg, the nutes i use do not build up salt AT ALL, i have been using this stuff for a yr and a half and have yet to see any build up anywhere, i have spoken to the rep for this company many times and he says that there is no need to even flush with these nutes, of course i ignore that.....anywho heres some more pics, btw i had to lift up the plants because i did not feel like moving all the plants out of the room and puling out the ladder to lower
