I have found Miracid to really work quite well in veg. I add 1 tbsp per gallon of water and really greens the plants up during veg. I've had problems with the more expensive, mainstreem nutes not doing all that well in veg. I was very disappointed with my last run with Cannnutes. And Miracid is way less expensive than the other products. Lots of micro nutrients.
