So I keep reading on multiple forums that FF sledgehammer can straight up ruin a grow.
I see multiple ways people are doing the FF flush. Some claim success, some claim total ruin.
From reading the instructions, you add 2tsp to a gallon of water and that’s it. Done.
Do you have to actually “flush” or rinse out the Sledgehammer out of the soil?
Can any remaining sledgehammer leech all your nutrients?
I’m tempted to just use PH’d water to flush
I invite input from all soil growers. Do you flush at transition? What if your plants are showing no signs of abundance or deficiency?
