I have had some really slow flowering strians it seems but have some new Northern Lights seeds that say 3 weeks veg and around 45 to 50 days flower. Well since I have hydro system and have made many mistakes I don't have any plants that have taken less than 90 days to mature and still then they could have used more time. Think I have been dealing with some very dominant sativas but anyway with 1000 hps and two t5x8 cfl units what can I really expect on the Northern Lights is the real question? Also can anyone tell me how high you can take ppm without the burn and what I mean is do you have to wait until very late into flower to move up from 800-1000 ppm and should you go above 1000??
