Stealth Hydro powder nutrients

everybody seems tobe telling me they are garbage, but they seem to be working for me, any comments

They are working fine for me also but i have nothing to compare it to, this is my first time in hydro, and my nirvana WW is in the 1st week of flower

I have fairly soft water here, it's natural pH ranges 6 - 6.5, I do a half pack nutrients + micros at reservoir change, it adjusts the ppH to about 5.8± and the remainder throughout the week as needed, usually within the 3rd - 4th day after the change.

Now in week 4 of bloom, I have had to supplement with FF's Beastie Bloom (added in 3/4 tsp per 6 gal res).

does anyone know what their NPK is on the powder noots?
