Hi i too am a first time grower and just a thought can over spill (too much) water leave the pots ie are there any holes in the bottom as my plants also started a bit slow and noticed leaves drooped at night time or too much water once i put a hole on the bottom side they did alot better as the water that the compost couldnt soak up it just left out of the pot.I used to water them twice a day and then was told to water once a day i did at night time b4 i went to bed hope this helps ? I had 4 plants but just killed one as it was male but 2 look def female. also look at web addy u been given in other reply as its well worth a good read laterz and all da best DEXY
