The CM veg is 680 and that doesn't change from the time I transplant until I flip to 12/12. BD is at its highest now during week three because I'm still feeding silica, PPM 1125/35. Fourth (no more Silica from here on) and Fifth weeks will drop down to 1080/90 even with the increase in phosphorus, potassium and week five elimination of nitrogen. Don't rely too heavily on a barren PPM numbers, what is important is how the plants are reacting to what you're feeding them. I share beefninja97's observation, your girls look hungry. New growth will be the lightest green with deeper greens on the aging foliage. That's the best way to evaluate what and how much you need to feed them. And, of course, following, within reason, your nutrient manufacturer's feeding chart. What nutrient brand are you using?
