Using Cal/mag?

 

[Holdemgodmode]

Not using cal mag suppliment yet, no.

My tap waters ppm is around 125 out of the tap

Cannabis is a cal mg hog normally.... put it under LED and it becomes voracious.

Cal mg... from the start under LED. Coco also can tie up magnesium....

Without running thru your complete grow, lighting ph etc....this would be my call...

PS, I ran fox farms for years with photos, when I jumped into autos a year ago I chose HF.

Halfway thru flower I was in a mess... after lots of checking, the soil pH had slid well south of 6. Was the peat and coco in the mix...I got her thru to chop, and switched soils. Haven't looked back.

Have seen lots of posts on the web on their QC going down.

So question
I have some GO cal mag organic suppliment.
Can i use this with my new nutrients? The Flora Trio. They are not organic

This one I can't answer, I run an organic line... maybe one of the guys using FN will pop in.

Magnesium sulfide (epsom salts) foliar fed will help as well.

up the feed strength, that's too weak now,.... looks like Ca defc. to me, but P cdefc. can show similarly,...
