Monitor tomorrow with your meter.
During veg water may not fall quickly unless off coarse you have some bushes.
The Ph and Ec will change, this is were I would read with ppm as it’s finer.
I did notice that the same nutrient water that was left over in a gallon jug had a much different EC than the water in the bucket, both had been there a few days. almost 1000 difference... the jug water was 2400 and the bucket water was 3400. I think the bucket had a lot of salt buildup or something, i had to do a lot of scraping to get whatever it was (salt or nutrients) that created a ring around the bucket, is that a good sign that i've been overfeeding?
