Lockout or Deficiency/Burn

Hey guys! Thanks for reading.
Im basically wondering if this is burn or deficiency, or lockout. I’m thinking more lockout than anything since I’ve already run into it once before on this grow.
50/50 CocoSphagnum mix and FFOF. Added perlite and mycorrhizae. 480w Meijiu board. Temps and humidity are fine, 40%rh and 83f max.
ive been using Botanicare pure grow and bloom along with calmag. I just realized today I may be over doing tha calmag a bit, 5ml/ gal.
7ml of grow and 15ml of bloom. I have another plant that’s loving this mix. They’re all on week 4-5 ish of flowering, I haven’t kept a schedule for this grow..

Any help is appreciated. Sorry for the weird wording I’m in a slight rush right now. I can always add more later if y’all need.
mich love and happy growing.

Looks like a lock out. Leaves are really dark

Thanks for the reply man! Just needed another opinion. They got water with calmag but nothing else but pHing today.

What's ya tap water ec . Then what is you feed ec aswell .

deffo a pH issue. Always see issues when mixing coco and peat media. Best to go with one or the other.

Find a way to test the soils pH and go from there.

If all else fails flush with pH water and calmag then on the last gallon make a balanced pH feed. Aim for a 1-1-2 ratio if possible.

I just got a ppm ec meter. Not sure about conversion math yet. If you know please inform me
My tap water was around 215ppm. Feed is 875 ppm.
There’s more math I’m wondering about too. I’m mixing 7ml of grow with 15ml of bloom. Let’s say it was a 1-1-2 mixed with a 2-1-1; what would those ratios be/how could I figure them out?

So for ratios of NPK you’ll see that your grow is something like 4-2-3 and bloom for example 3-4-4 or whatever. Basically mix so those numbers are as close to 1-1-2 as u can,

I got that, but how do I know the total value if I’m mixing different quantities of grow and bloom?
Thanks for reply, dont mean for that to sound harsh haha.
