I think it's to high but of they like it cool. If/when u run into an issue u know the first place to look. 6.5ph is best. Stay 6.3 -6.7 ph if u wanna do it correctly from start. Certain nutes they can/can't uptake if its not in the correct range. Then u'll be wondering if its nute lock and chasing your tail if u see a deficiency. Im just thinking why not do it rt. Make it easy on yourself.
Honestly I might need a new pen this one take fucking forever to somewhat settle and some reason it fluctuates by .1-.2 I paid 40$ for it from local shop
