yeah definatly this was something i had no idea about, for some reason the organic nutrients if u add to much it becomes a boron def. instead of it showing nutrient burn, but it kinda is becuase the leaves are pretty much burning from the effects just a different kind of burn. im going to take down the ppms a bit i was waiting for a nutrient burn to show up but instead i got this.. eh figure..at least we are one up on the problem list:thumbsup:
