My plants are at day 57 and the big fans are starting to go light green/slightly yellow
I've had a PH meter since the start of the grow but never used it
I calibrated the pen ( which needed no adjustment)
I buy my water and has a ph of 5.9
With nutes added it's 4.4
and the runoff is 5.8
Would appreciate any advice on those figures, any other info i'll be happy to supply
