It can't be brown into sativa, Indica , and hybrid... everything is pretty much a hybrid anyways. What may burn one indica dominant strain may not burn another. It would have to be strain specific, which means you'd have to formulate and test for every individual strain whether it's Indica or sativa dominant. Saying you're making food for sativas or indicas is a lie that only a noob would believe, that's like making one pair a shoes that fits all mexicans... I'd stay away from trying to make food for every strain.
