veggii Reviewed by veggii on . PH questions Hi, I have a few questions for all you growers experienced in the indoor, soil growing area. I grow in Costa Rica, obtaining canna specific nutes and soils isn't possible. However I have multiple successfull harvests here and am growing a purple kush strain from the bay area that generates about an oz per plant for me under a 400watter. I am trying to perfect my grow though as I have been having some issues with yellowing, crispying and dying of the majority of fan leaves around week 5. I Rating: 5
