Ok I like to grow from seeds but am attempting to clone some of my Purple Kush before I flip them into flower. Have had 8 cuttings all in rockwool have been for 10 day some are visibly yellowing I am told this can be a good sign but with no roots showing am curious if they are dieing off? they look to have some new growth. I am starting a Jack herer run from seed but hoping to save some of my PK any advise would be helpful. Good with seeds but clones are new to me.
Thanks in advance
