I wish it was that simple Cres, I know it isn't the PH, the tap water comes out at 6.9-7, and after nutes, needs very little adjustment to hit 6.6-6.7. Also there is no indication of lockout or burn.... These plants have had very little stress at all besides the dry out when I was gone; my Plushberry plants outside were pretty much tortured with hot spells and drying out every day in the middle of summer, also light pollution like crazy; there was never a hermie issue with them though, so unfortunately I'm thinking that this cross may be really easy to stress out.... The good news is that the breeder female hasn't shown any balls and is producing nice big seeds for ya to play with. I like the way this strain grows, very foxtaily, it would be a shame to kill the project....
