I would love to get some clones I have before and they got roots but had no idea how to feed them like how much etc my phone won't translate the page of that site even though my mum is Dutch lol its a pitty do they have there own genetics or?
1/4 strength nutes should be fine for young cuttings when you see roots and really just treat them the same as your bigger plants, but until you have roots you must keep cutting damp with normal tap water or very weak nute solution.
Not to sure about there genetics just know i haven't heard of them going hermie (hermaphrodite) like some of the other breeders. had a couple of crops fucked up from bad female seeds that produce male flowers and ruined the full crop.
Its nice to have cuttings from a good source or grow your own mother from seed for cuttings.
The white widow x big bud can take some punishment and still kick ass! super big frosty buds mate and easy to grow.
