Yes on the advanced nutrients. Do not stray from the ph perfect line up and there is no worries of PH levels PPM is not a worry. I use sensi grow and bloom PH perfect and voo doo juice, sensizym, bud candy, and big bud, over drive , nirvana and rhino skin not in that order but that is what i feed with. I start out with 1 mill a liter of the sensi grow a/b and voo doo at day ten to 15. On day 15 I then add bud candy and sensizym to the above, On day 20 I add Rhino skin to all the above make sure you put this in first and let sit for a hour it breaks it down better this will all do until day thirty. I use 1 Mill per liter of all the above until then. On day thirty I switch to bloom sensi a/b at 1.5 mills per liter 1 mill of voo doo 1 Mill of Big bud 1 Mill of Bud Candy 1 mill of sensizym 1 mill of nirvana 1 mill of rhino skin at day 40 I might bump up to 2 mills of base nutrient sensi a/b but that is if the plant is showing no nute burn. On day 45 I switch from BIG BUD to OVERDRIVE 1 mill per liter and I add Bud Factor X which is dam expensive but needed. That is what I run until flush. I never let my temps drop below 80 degrees and never let the rh go above 50 the I usea 8 inch inline fan and scrubber to exhaust I use a 6 inch inline fan for ventilation plus passive intake I Am a firm believer in lots of air movement I use 12 inch fans five all of them going at all times to in a tent a little bigger than a 4X8 and of course 24/7.
