update i was going to write about 4 plants, out of 20+ in flower now, here is a g13 clone i took off her mother on her death bed i was lucky to save 3. this strain has alot of history, maybe a goverment grow, dont no for sure where its orgin came from, what i do no its a very hard strain to grow,(at least for me so far) i just wanted to share this with site. 1st and 2nd pic are g13 about 3-4 weeks in flower 3rd is purple kush almost 7 weeks in and the 4th is a group of plants that are just starting to flower, i was hopping someone could help, see the light green color where the pre flower is starting, is their something thease plants need, some nutes more or less? or they ok as they are. anybody have any questions feel free to ask thank for looking,
