Hey
@BytownGrower. I use the same kits to check my stuff. I just loaded a pic on my grow diary Mixed-Pack Auto's. To answer your question, for me, I said for me I would not feed much thru water. You will burn them. Look at mine .I have them all on the low scale then lightly feed thru the water. Your grow medium looks like it has basic nutes according to the vial test. I would say yes it's about medium. Like I said I wouldn't feed much thru water. Very very lightly. Hey I'm a newbie and learned, burnt some plants up!! Just tryingto help,Peace and Love.
