Best nutes growing under LED?

[login]

I've noticed on some of my plants I get this reveg looking buds half way into flower after I cut out the calcium nitrate I start to get calcium def so I add calmag. But the cal mag has nitrogen and causes fucked buds shooting out single leaves all over the bud.
This only happens under LED, never under HID using jacks 321 and same clones.

Why don't you use gypsum instead for calcium

I'm in rockwool blocks, on dripers. Can it be packed on top the rw block?

I run my ro water through calcium carbonate but that only adds 30 ppm calcium back to the ro water

How can I add nore Calcium back to ro?

Never grown in rockwool but have you tried to supplement extra magnesium? Do you have pics

Why are you cutting out Cal Nit half way into flower? You feed all the way through with 321 and taper down the ppm the last week.

Well because calcium kills quality, and nitrate kills quality.

Calcium Acetate.....Is a good way to add it without mess other nutrients, you will find it cheap too

Sorry, just saw the tag @2Bad

@login, can you provide a pic of the reveg you are seeing?

So you have a tent? with rockwool cubes and drip lines, which I guess drain to waste? All that is identical and just the light changes and you have problems? Why are we thinking this is related to nutrients?

What LED are you using?

Any potential light leaks or LEDs stuck on or a led on the driver or something that says on all the time? I'm reaching here because I don't truly understand the issue without some photos.

I use General Hydroponics Flora series (FloraMicro, FloraGrow, FloraBloom) as well as Armor Si for added silica. And during flowering I add flower fuel to the mix.
