hey in a 50gal we use Sensi products, in our vegging tent and flowering. for the veg we run about 900ppm to start and see how the babies enjoy it. Then after a week or so we add more of the sensi grow. It's a 2part liquid A&b mixture, for our flowering we run roughly at 1700ppm in our flowering tent, we've been using this formula from the start and have sucessful growth. We also run Co2 in the flowering tent. As per we have the business to do so. And as you've read I'm fighting spidermites 
they're not webbing but they are there
