What should my PH Levels be at in an Hydroponics system? And is there a difference in veg Ph and flowering Ph? Iv attached my little color chart to see if anybody can tell me where I should be
Like GoG said, 5.5-6.0 is good for hydro. You may even find a point that does your plants best; for instance mine is 5.8-5.9. There's no difference in veg and flowering PH, other than the PH changes that could result from other factors, during veg and flower.
