" chemdogs and thc bombs and they are both in their 3rd week and growing super strong ". If these are at three weeks without signs of nute burn, etc, then I disagree about it being the soil. And if he has used the exact same technique with the other plants, I'd say that precludes light burn and temps also. I think he's right, he's either got some bum seeds, or they got contaminated with something. I'd test the soil in the pot your using with a seed of a different strain, just to see if it is something about those particular pots of soil also, never hurts to eliminate all possibilities when in doubt.
