What does anyone make of this???????

There is a purply colour appearing to spread accross the leaves, shown in the photos, and im not quite sure what to do about it, has anyone ever seen this before, or has anyone got any recomendations as to what i should do?View attachment 1971140View attachment 1971138View attachment 1971136

wouldn't worry about it to much at this stage considering its a seed. but im gonna guess and say to much potassium in your soil....a or b your strain is just a little sensitive or an aggressive feeder. Hopefully it don't develop into a burn. If your to concern you could always carefully pull up the plant and transplant into some coco medium.
