morning sun is the best sun.....just in case you didnt knowMoving them inside at night is good too man, I bring mine in just cus the dew and to get them 12 hours of dark as well. What strain?
Nope they are OD. Not sure of the strain, they were clones from a 'mysterious' source.....phosphorus deficiency will cause the stems to turn purple, not the leaves until later and major deficiency.
