Florabloom help.

Hi guys im new here and was hoping someone could help. Currently I am using the FloraGrow 3 part nutrient solution from GH. Well I have not been paying attention and have run out of the FloraBloom. It will be at least a week before I get more and im wondering if there is something i can use in its place for my veggies(yes im actually growing vegatables). Im in a small south eastern community so we only have Lowes and similar type stores. My nutrient level will drop way too low to keep my plants healthy in about 2 days and I cant ship something in that quick without considerable expense.

Any help would be appreciated.

Jeff
