droopy curling up and dying?!?

hey people.

This problem I'm having has probably been addressed before but I can't find it so could someone please help me here.

my plants bottom leaves are dying and I'm not sure why.
I have two plants and they get the same fert but only the one is having trouble?

could you please take a look and tell me what you think it is
The fert is a mixture of sea grow and Multifeed (classic) 2.1.2 (43)
I have followed the directions properly and give it to them as they need water. Usually every 2nd day.

Thanks for you help guys

probably over nuted. Dnt feed them every watering.

shot man.
but any idea why only 1 out of 3 died?
they all treated the same and come from the same batch of seeds, same mother plant.

you used to much fertilizer man

ok but can any one tell me why only the one died?

hey, found out what was killing my plants.
after another one died I had a closer look and it seems my fucking dog has been pissing on my plants!!!
so that mystery has been solved.
thankfully I have convinced my folks to let me build a grow cupboard so this should never happen again...fucking dog!!!

lol...dog piss thats funny !!!! poor plant.
