Hi all I have about 2weeks left on my grow and I’m gonna start flushing in a few days,I’ve been ph ing my feed all the way through flower with a value of 5.9 to 6.0,now over the weeks I’ve been spotting a bottle of ph 7buffer in the corner of my room but thought I don’t need to use that,the pen is fine,so guess what I did today,I thought I’ll just av a look if my pen measures a 7 ph with that buffer,now this bottle of buffer is about 2 years old so I don’t know how accurate it’s gonna be,but long story short is it measured 7.4, I was thinking if my ph has been that far out all flower,I would have had some sign from the plants but they look awesome,if my ph was out by so much what would the signs have been?
