Right not experienced grower but I studied a lot, it’s genetic problem, either you causing it with temp, nutes, light .. stress or it’s inbred and genetics already presented faulty from the seed. Now it all depends what is causing it, if it’s purely cultivar problem then it might be ok as long as it doesn’t carry any herm traits with it, humbolt a freak show was bread by various different visual traits such as 3 leaf I’d say :)
