that is not a sign of mag def at all. mag def will show sings by mustard yellow tips and edges along leaves and gradually yellow inwards. alot of strains have natural purple stems.
It might be mag im leaves are like mustard on 2 of them, but I appreciate your input . Everyone will assume this n that but thats why theyhave this so all thought can be brought together and sort of n someone will learn . I just placed a blackberry in napkin today I have a total of 4 bag seed growing but this is my first strain I kno for sure what it is cant wait to put in dwc as one of my girl is in n loves it lol the other 3 in soil using GO and GH nutes
Sorry for the rambling just thought iwas mention
