well without proper info from the grower its hard to tell whats wrong with a plant.....but in my opinion, where should we start.....
1. looks to be over fed, due to the gold tips and yellow lower leaves, i would say you have been giving her nutes with every watering, correct?
2. looking at the curled under leaf tips ( or Rams horn appearence they describe in any of the hundred plant problem solvers listed on this website), She is showing you she is too wet, so stop watering for a few days and let her dry out.
3. Due to the over watering, she probably has saturated roots, turning into a pile of mushy, anaerobic material that will choke out the rest of the plant, if the gnats don't eat all the soft roots first.....
4. Lights....Go to forum, grow room design, and read any of the stuff in there about proper lighting, and distance from plants. ALSO CHECK OUT THE INFO ON PROPER AIR CIRCULATION....
In conclusion, i would agree with the rest, throw it away.......Read the site, gather knowledge, then start over. I know guys in malaysia that have access to seeds, if you found this seed, i am sure your friend will sell you another bag and you can germinate another bagseed to start over.....
GOOD LUCK TO YOU SIR
