Advanced nutrients sensi in biobizz nute adjustment

[InspireMe]

Hey guys, I wanted a second opinion on my feed. I've got very small signs of too much N. I have had for the whole grow pretty much. It's not toxic but i want to get it dialed in a little more. I'm growing fastbuds: blue dream x2 and a Jack herer. Week 2 of flower.

Anyway... my current feed is
sensi bloom B 1ml/L (NPK 2-4-8)
Cal mag extra 0.25ml/L (4-0-0)
B52 0.5ml/L (2-1-4)

Burn isnt serious, I've just got dark sugar leaves that claw, no burn. It's just not perfect so I want to get it dialed in. I bought some Big Bud to help cut out some N (0-1-3)

So my thoughts on new feeds,

Option 1:
bloom b 0.5ml/L
Big bud 0.5ml/L
B52 0.25ml/L
Cal mag 0.25ml/L

Option 2:
Bloom b 0.5ml/L
Big bud 1ml/L

Option 2 cuts the majority of N out, but I also lose a lot of good nutes so I dont know if I should go ahead.

Another though was switching out my bloom b for my grow B as that has an NPK of 1-2-6. But I'm unsure if that will be detrimental, any opinions on this?

My ppm is pretty low, it's always between 350-450ppm. I water to 20% runoff (biobizz lightmix soil) I'm certain I dont have a buildup.

Any other suggestions would be great ????
Cheers for taking the time to read and reply ????

That cal/mag is the problem imo. That's a lot of N in it.
What kind of water are you using?

Yeah I've dropped it down over time but it's still not had any luck I was at 0.5ml/L then dropped to 0.25ml/L. I'm using filtered water at 0ppm (zero water filter) I'm under 2x viparspectra p1000 LEDs so I'm reluctant to cut cal mag completely. But I agree with you, it is definitely an issue. I dont know why on earth AN would make it with that much N in it. It's more than the base grow A/bloom A which is supposed to be the N source.

as above; you don't need to feed cal mag that often, it's a bit of a scam really
that's probably the issue you're having, i'd just cut the calmag out and only use it sparingly, if at all.
i've completely cut it out of my grow and it's done nothing but good things

Thanks dude! I'm a pretty new grower.. I've seen a lot of things about it being important based on water type and if you're under LEDs. I've got 0ppm water and under LEDs XD so figured I best give some. Do you disagree with this then?
