I have pH down, because my water is 7+ if I make a small solution up and place it in a little shot glass will it be okay ? Or I have seedling soil which has nutes in it but very little to stop seedlings burning, and add some tap water which has been taken down to 6ph I can't really do the cup of water trick due to visitors tomorrow if there is an 18hour window, I ain't as high tech as some of you guys so if it goes straight into seedling soil well moistured it'll be okay ? Don't want to over shot the timing on the cup of water trick and destroy my seed ?
