They should be all green gelato auto rqs but one has a darker and different colored flower from the others. Who are you? Who are your parents? Did you get more from mom or dad? Strain .... question after question 👆😁
Unfortunately you can get multiple phenotypes from seed suppliers. Same strain but from different plants. I had 12 gelato seeds and there were 4 good phenotypes in the batch, the rest I were good, but not equal.
