marijuana actually is used in the treatment of glaucoma as it reduces the pressures in your eye (in glaucoma you have high pressures) i know this cuz i have a slight chance of getting glaucoma >< (possibility of going blind)
lol dun worry man u got views ... i just don't got much to say but wow lol. (im actually pakistani so im really excited to see how these turn out). i might grow some just cuz of the name.
still seems like you might be overwatering them. try and get some pics up yeah? lol.
also try and get us more info of your set up and stuff. temperature, venue, humidity, ph levels, and soil.
Honestly ... the problem was just everything that was wrong working against you. high humidity, over watering, terrible soil, bad ph levels, and also your set up with cans and milk bottles. You really need to have bigger pots so that way the soil can soak up more water and the plant generally...
