Peters 10-30-20

So I think I was sent the wrong bag but I have this Peters 10-30-20 and I’m curious if I can use it in my DWC? I thought I bought the 321 but I guess I got this?
can I still use it in my DWC? How much per gal?

Howdy EzPz, I do not have any experience with that brand, but it's ratio is close to the GH MaxiBloom (5-15-14). As for the dosage per gallon, I recommend that You contact the manufacture for the recommended amounts. If the manufacturer can not give the recommended values, start with small amounts (1/2 to 1 teaspoon per gallon) and work up from there. The maximum dose for the MaxiGrow is 1 1/2 tsp per gallon, just for reference.

I use the 5-12-26 as part I of my 3-2-1 mix.
The 10-30-20 would be OK for an initial bloom booster, but it has the wrong proportions for use after that.
Too much P.
