hello my friends!

i have a question on PH

right now i have an aerogarden and im trying to make sure the ph is right

i put in 2 milliliter of some general hydro grow nutes in the res and i used some spring water i bought at the store so i draw some water solution out and test with phenol red what color should it indicate???

i read some place you do one drop to 10ml of sample water but not sure

googled it with alot of different scales and colors ? help sooo confused?

you need to use the scale for what ever brand test strips you have. ph should be around 5.8
