Quick question with the jacks gang. Im using tap water so i got the part A recommend for it. Instead of 321… should i be using 5 2 1? Am i reading correctly 🤔 ![Screenshot_20221209_223424](https://global.discourse-cdn.com/growingmarijuana/original/4X/1/5/e/15e47e5a50564593de50309ce5573621079c7b94.jpeg) ---

I use tap water and RO water. I use a, b and Epsom salt. If you get the one made for tap water (15-5-20) thats all you need if I’m remembering right. It’s an all in one nutrient. You don’t need part b. Some people say add a little epsom salt, but it’s supposed to have all the magnesium you need. So you just add 5.05 grams per gallon and you’re good to go. ---

> [@Blackrose](#): > > Am i reading correctly The schedule you posted is for 15-5-20. This is referred to as Jack’s TAP formula. It is designed to be used with tap or well water. For a gallon of mix use 5 grams of 15-5-20 and 1 gram of epsom salt. Mix thoroughly, ph, check ppm and adjust accordingly. It is not the common 321 formula ---

> [@Spiney\_norman](#): > > They routinely deeply discount Jack on their eBay did not know that. When I first switched to Jack’s 321 I searched and it had the best price with shipping for 25# bags. I try to find what I need locally first then anywhere but amazon if I can. ---

> [@sandune](#): > > Ive got enough for 900 seeds I think!!! A while ago I did the math. How many gallons can I get from 25# bags using 3.6 / 2.4 / 1.2 grams per gallon.

@beardless I like your local first approach. I only buy from Amazon as a last resort also. Hate the way they let the vendors lie about the products, and take advantage of the new grower. [Next page](https://ilgmforum.com/t/jacks-321-where/96037.md?page=2)
