I wouldn't worry about this unless it gets worse. if it does, you probably shouldn't have used miracle soil. many people that use it come here or other sites saying they have problems. mg soil tends to be on the hot side, loaded with ferts for long term feeding. once the plant is in the soil, if there's too much fertilizer the only thing you can do is flush it with a fair amount of water, then let the soil dry out quite a bit before you water again. what you have could be due to a deficiency or overfert, it's hard to tell, or it could be insects or a genetic flaw in the plant. hard to tell right now. the orange areas are pretty large. you have some leaf yellowing and the green areas on some of the leaves look to be a little too dark green, so if I had to choose now I'd say the soil has too much fert in it. this can cause more damage to a plant than under feeding it. foxfarm soil might be a better choice next time. it'll be interesting to see what others think.
