Please help, im very worried :(

Hello clever people.
I have recently been given a cannabis plant, its about 3ft tall, i have no idea how old it is, and the stork is pretty wide.
When it arrived one side of the plant had less growth than the other, it has a decent amount of buds on it but some of the leaves start to get browish greyish spots on it, and then the leaves turn yellow or just dry out.
It is now starting to spread around the plant.
I have not given it anything apart from some tomato feed because i thought it could be phospherous deficincy and i saw a tread said try some tommato feed.
I am unable to upload pictures at the momment sorry.
thanks in advance

Im not an expert grower by any means, but most problems can be found with a solution via this link in the plant problems forums. Hope it helps.

First off did the discoloration begin grayish and then turn brown or is it a mix where some areas are gray and others brown?
　
What level did it begin on, the upper/top, the middle leaves or the bottom leaves and when it spread what area/leverl of the plant did it hit next?

Just going by grayish the below popped to mind but without more info and or clear pictures it is a guess at best.

B - BORON (B)

Growing shoots turn grey or die. Growing shoots appear burnt. Treat with one teaspoon of Boric acid (sold as eyewash) per gallon of water.

i have had a look at that thread before, my plant is mostly like figure 12 with the phospherous deficincy.
Any idea how i can sort it out?
Sorry to sound like a noob, im a member of other forums on all sorts of things, and theres nothing worse than a noob asking questions that have allready been answerd before, but i have looked around.
