I did noticed this too!
When they entered in flower, with PH on 5.6 they begins looks with deficiences, and reading about it I did take the conclusion the PH was too low.
One strange thing is, the PPM is getting higher and PH too, but the water is falling… I was following the chart bellow was one of the reasons what I let the ppm lower in range of 600 ~ 750.
I will check the ppm and ph soon and update here… I guess it will rise slowly… until the end of day will be on ± 6.1.
I need change de res water… just waiting some rain while I dont made my OR filter.
Check out some of my journals on here,
I will do this!
