try and reduce your temps to around 80.... i have all most the exact same set up with the same strains! what hieght did you begin flowering at? those big bud and NL can easily handle 1200 ppm week two.... they max out around 1800 ppm or so. but these plants will not be able to focus on photosynthesis if the temps are about 85 and co2 use stops at 85. i am using 4 600watts instead of 2 1000watts and the only other diff is i switch too ebb & grow from ebb & flow when i go to the flower room. I flower at around 2' plants are as tall as 64".
