goofy ass plant.. look.. help?

Okay.. i've posted here before about this plant. this isn't my first grow, but i don't understand why this plant is so different. at 15 weeks its only a few inches tall, producing buds, and it's turning purple. i put it into the 12/12/ cycle at about 7 weeks or so. i took it from outdoor to indoor, so the plant shocked a little from the transplant, and then resumed growth. when it hit 12/12, it began to grow noticeably every day, and then recently kind of slowed down. it is still only a few inches tall. the plant always looked healthy until just the other day, i noticed a little bit of crisping around some of the edges. my guess was a ph inaccuracy and temperature droop. i keep it between 60 and 80 during the day, but at night it gets a little cooler. i use regualr shultz plant food for all indoor species found at your local supermarket, and it has worked for me in the past.. i'm just kinda stumped. i tried to put some pictures, but they apparently were "invalid file" for whatever reason..
i don't wanna kill this plant, but i want to get done with it so i can start my hydroponics system.. im also a little worried about how much yeild im going to get.. is it worth it?

lets see some pics. if its growin buds i'd say keep it around. it might suprise you even more and be the best bud u've eva smoked lol

That's it mate,it sounds to me that the 2 incher is finishing and what you see is what you get. Could be really potent though!! Showgirl
