you have 2 different strains of OG.....the purple kush will be a small short plant.

The OG Kush will stretch out in flower (when you cut your lights to 12/12)

The OG that I grew the leaves were droopy too but after I started cutting the lights they perked up

Dont cut the leaves edges .... your plant will put on new growth.

I would get alittle better light set up mabey a 400 watt MH:thumbsup:
