All of my caramel moruga scorpions (4 of them) and 7 pot bubblegum large (2 of them) have leaves similar to eachother. The rest of my peppers dont have these purple/dark colored leaves. Im wondering if this color is genetic or caused by me overwatering or me doing something else wrong. I have fed them fish emulsion twice in the last 16 days and keep them under two t8 bulbs. I water or feed about every 3-4 days but im terrible at judging dry soil. My other 10 plants dont have these colored leaves and look fairly healthy. Any help would be much appreciated.
