Looking For Good Phosphorus Supply

Hi everyone just a quick question I have a single plant in flower n would like to fatten the buds up n have read that phosphorus is needed for dense resin coated buds. I need to know Wat I can add to help with this.
The only grow shop near me got closed down due to the crop in the basement n nearest one is miles away n I have no car . I have a homebase near me n a wilkos is there anything I can buy at either or anything around the home o could use?
Thx n I'm sorry if thus is a stupid question but I am a complete noob lol
Cheers

Go look at what they've got for fertilizers and look for something that has a high P content? I couldn't find anything at home depot the other day when I went...so I'm just sticking with my shultz 2-7-7+micronutes cactus feed

The only thing I can find is tomato feed at 6-2-4 but I thi.k its to weak or is that ok for a single plant ?

That tomato feed will work very well

Cheers boneheadbob is it ok to mix 1ml to one litre I read that on a diff forum ?

lowes has some high P orchid food 11-35-15. as long as your not goin organic.if thats the case use bone meal. steamed bone meal and fish bone meal are the best but some regular lowes knows shit would work fine. bone meal takes a while to break down so depending on how far you are into flower it might be too late for bone meal.
