Zinc problem help

Ok, i looked at the plant problems thing and found my plant has a zinc deficiency, what do i give her to give her zinc, or how do i solve the problem? I dont know the ph of the water as i dont have a ph meter, she's about 2 months old, still in veg, im giving her a long veg for more bud as she's my only plant right now

edit: let me rephrase that, where can i get chelated zinc and how do i apply it to my plant?

Shes dirt btw

get a ph meter if you dont have enough a little fish tank one will do and you can get it at any place that has fish equipment between 5 and 10 bucks. and for the other question they should have at any horticulture store
