One other question I have on water. My ph is low. Haven’t ran it through my RO filter but from what I know that won’t change. Last time I checked my ph it was about 5. Should I add ph up when I water plan. What ph are u looking for when drenching and watering. Should all drenches be dunks?
Don't give it a second thought! Please do not, under any circumstances use pH up or pH down. Useless, stupid, ignorant, unnecessary and harmful! The soil is buffered and the stuff living in the soil makes its own acid as needed.
It is preferable to dunk in veg for sure. It's pretty hard to do it in bloom, so use a saucer and fill it up, putting the rest down the top. 1 gallon of drench per each seven-gallon pot in bloom is about right.
Read the directions! That's where you'll find the secret information to get you fake plants.
