Don't forget that we have 2 soil grows going at the same time, so it will be needed. Thanks for letting me know about hempy not needing it. We still have our ph up and down kit thanks to PW. And, thanks to Toasty, we have pH down crystals from Earth Juice nutrients. We also have Cal Mag, thanks to Dom. Other than the talking tools, I think we'll be set.
Oh you're just making my life easy at every turn baby!
So... I use Earth Juice PH down. Depends on your starting PH... but I assume coming from a municipal source it will be very close to mine... so you'll want to use an every so slightly humped 1/8 tsp of PH down per gallon.
Honestly, chasing PH gives some new hydro growers a touch of grief. We get to avoid any of those dances.
