PH drop from 5.8 to 5.4 over night every night
PeppaWutzstarted grow question 4 years ago
Watertemperature 22 °C, 100 L reservoir (changed every week),Start EC 1.0 and drops to 0.8 at end of week, Ph adjusted daily to 5.8, tent temperature day 27 °C and at night 20 °C, humidity 55%. I add calmag to EC 0.4 and canna aqua until EC 1.
Why does my ph drop over night?

GMSgrowsanswered grow question 4 years ago
Your ph is dropping due to your plants up taking more water than nutrients. It leaves a higher concentration than when you first mixed. If they were taking more food then your ph would drift up. I used a growboss ph & nutrient meter for constant monitoring when I grew rdwc. Try lowering your ph to 5.8, that is the sweet spot for veg. 6.2 6.3 in flower. Cheers
