yellow leafs

hi my plant is now about 3-4 foot and i have only had it for about 3 days (got it off at mate ) but most of the leafs have gone yellow and i have pulled them off but now the plant look a bit bare what am i doing wrong

also i water about 250ml every day to much or not enough she also has about 20 hours off light a day

too much water, you should only need to water every few days, if its really drying out that quick then you need to repot the plant. and a plant that big needs nutes.
