Are u using calcium nitrate and calmag? If so thats another issue u need to address! U don’t need both!
Calcium nitrate is the nitrogen component of master blend.
So what was in the bucket was your standard masterblend mix, with nutrients, calcium nitrate and epsom salt. Its not had anything added to it in about 30 days, this plant really hasn't drank much water, they really don't until they get into flower.
So my assumption had been it had used up all the calcium in the water, which is why I added more calmag.
But fuck it, you guys got me all wigged out now, I'm just gonna dump the bucket now.
