5.6 to 5.7 is acceptable, on the low side for hydro. Ideal is 5.8, however calcium is more available at 6.0 - 6.2.
I typically keep it at 5.9 if I can. If you go over 6.5 you burn, under 5.5, you burn.
I am not sure on coco, but 6 to 6.5 sounds right to me.

the charts for soil are higher pH
What I see there looks identical to high pH in hydro. Which indicates N def. through nutrient lockout. We will have to wait for Waira or Namvet to give a definitive answer.
THANK YOU FOR THIS CHART I DONT BELIEVE ITS HIGH PH BECAUSE I NEVER WATERED WITH WATER HIGHER THEN AROUND 6.5 NEVER OVER BUT MAYBE I NEED TO BE MORE CONSISTANT WITH THE PH
