Its because its a tropical sativa. Low feed, max 500ppm, and very poor genetics. I learned this very late in the grow. Believe it or not, I did snip all the lower branches on the plant underneath the screen. Pictures cannot illustrate how massive this plant was. If you look at tropical sativa's about day 60 in flower (search on google) they aren't that much bigger (but mine still can't even compare!).

Its a 250 watt hps by the way, with a lot of flourescent lighting added. Nutrient shelf consists of GH maxigrow, GH maxibloom, liquid karma, superthrive, hydroguard, kool bloom, and cal-mag+


I overdosed her on N, during the beginning stages of flowering which decreased the yield as well, had to buy a 0-10-10 nutrient solution to be able to feed her max 500ppm with mostly P and K and no N

also, i was needing to change my lights to 10 hours on, 14 hours off as needed by the breed, I learned that too late as well

If i was ever going to grow a tropical sativa again, which i'm definitely not :P then i know a little bit more about them and would probably get a little better results, but i am NOT going to wait 120+ days! no way!

If you could think of any way to improve my setup (besides the obvious things like upgrading my 250w) PLEASE! I love to constantly tinker and improve
