well here i go once again lol ......... now i'm on the fourth day going into the first week of the flowering phase of week five.. i'm starting out on using big bud advance nutrients along with the flora series. I sorta understand the concept of breaking down the amount of nutrients needed to flower using the flora series, but now I would like to start mixing in big bud. BUT the only problem i'am have'ing now is the ppm's .since I do'not have the ppm tester. BUT I do know that you suppose to a just it around 1200 ppm through the flowering stage ... so how much should I mix to get 1200 ppm's.
