I'm not mixing the nutes nearly as strong as you are and top out around 1300 ppm max.. I also ramp up during weeks 2-5, dial it back in week 6 and use nothing but water (around 5.8 ph) in the final 2 weeks.. basically mimic the new nutrient calculator, but not as strong.


I used to practice dropping the lights closer to the plants.. after burning the shit out of them I stopped and reverted to uber simple and fixed mounted the lights.. so in week 1, my plants are typically 3 - 3.5' below the lights and everything ends up stretching enough during the first 2 weeks they end up as close as 12" from the lights on some strains.

Since you're spending all the $$ on Advanced.. have you tried calling the toll free help line? The person that answers is VERY knowledgable and typically starts answering the help line about 12:00 Pacific..

Hope you work this out!

Peace, Farmer Rich
