if you bring the temps down leaves can turn purple on almost wvery strain, it happens in any kind of plants i can notice various kinds of plants (not only cannabis) having purple hues on the really cold days.
Some strains r genetically purple (purple buds) that always grow like that or have purple phenotypes
rottenPauL Reviewed by rottenPauL on . This may be dumb but Is there any type of grow factors taht can trigger purple leaves/buds (ie foods,climate,etc) or is it just genetics? Ive heard many different things, just wondering if anyone on here knows the facts. Adios. Rating: 5
