Thanx 2 everybody, you have all bin a massive help,

I flushed the soil yesterday and the water was full on yellow, i take it thats all the fertilizer coming out, now my question is how long untill it starts looking better?
at the moment it dont look better, if anythin the lower leaves have started to shrivel.
Is that normal?
anywayz like i say will it start improving quite quickly?
Cheers 4 helpin out people.
