Bro after i add my nutes, the ph is down around 4.3 . I then need to add much base to get it up.

I dont care WTF anyone says. I've seen a difference since last grow. Last time i used the tub and I had some deficiencies during flower. This time I'm using RO and the shit looks healthy as can be. Same nutes, same everything. You tell me what happened. OIh yeah, same strain(clones) too.
