I have 4 hindu kush and 2 blueberrys under fluorescents 18/6 hours of light, they are 3 weeks old, about 10 inches, got them as clones from a local dispensary . the problem is the kush is already starting to flower!! but the blueberry isn't, how is this possible? there both under the same lights. im gonna up the lights to 21/3, and hope that takes the kush back into veg, sence there way too small. this is my 1st grow so any advice would be very appreciated.
