Is this a sign of nute burn?

Does not look like nute burn.
Here is what it looks like but more pictures needed.
One question. Is this a clone you picked up local?
Sometimes pathogens can be ruled out by grow type as a lot of things look the same
Here is another link for reference

No.
Yeah local clone out shop, at first I thought it was a chlorine def so upped my micro dose then I saw something saying nute burn sometimes looks like this and I got curious if I was making it worse by upping micro dose

Plants need a very miniscule amount of chlorine, relatively.
Yeah I would have thought there would be enough in just the tap water alone.

Most likely it does, but a water quality report, would take the guesswork out of it.

Yea it's not nute burn. Kinda hard for me to tell from the pics what you got going on though.

Yeah I saw this yesterday it did look similar! Doesn’t make much sense as I’ve been feeding it enough bloom I’ve cut down my N to a third of recommended dose and do 2/3 micro then full strength plus some for bloom, (in flower obv )unless it’s from early flower where I did feed veg nutes mainly for couple week, maybe it’s just still got the signs even though now it has enough? I’ve only been at this year and half so still learning a lot.

My thoughts - perhaps what you are seeing is aging of a previous nute deficiency. However, if the purpling continues to worsen and you are feeding bloom in normal-healthy amounts, then what micro nute excess or deficiency could affect phosphorus uptake? Is your soil pH correct? This is the pickle sometimes if you don't have the basics(which I hope you do) down pat. Ability to test soil pH is probably one of the most important troubleshooting methods because it can eliminate or tell a lot of issues.
Is the purple splotching in leaves on lower branches or throughout evenly? The only micro nute that I know of(always leave room to be wrong lol) that can affect phosphorus uptake is too much Iron, which is quite rare.
Attached are the 5 graphs I use to help figure these things out. Granted someone who knows everything about the grow can use them more effectively than an outsider, so cheers growmie!

If im honest i dont usually check soil ph as i just ph my water to roughly 6.3 and make sure ec is in check for life cycle and i dont usually get any issues with my usual method of nutes ( i would have the base nutes and some additives for seaweed , pk, humic, ripen etc) but i wanted to try just the 3 bottle approach. The plant is budding nicely and building trichomes i just cant get over the red leaves ,like I said I’ve got a lot to learn only been at it 18 months or so.
Those pics are really helpful
In the long run for other issues too so cheers man gonna save them

What are the temps? Purple blotching like that is usually a result of low temps
This is actually what my friend said to me the other day and it does make perfect sense. The temps did fluctuate because I left a window open (wasn’t too cold for the plant not to grow but was a big enough drop) I reckon 16-18degrees with lights off.

Aye that’ll be it mate, don’t worry. P deficiency starts at the bottom leaves. They yellow at the tip towards the base and soon turn grey/brown crispy with some green/yellow left on the leaf.
I got it this run too when my temps were around 15-16c at night. Hard to make out in the photo but it’s the biggest fan leaf closest to the camera has purple blotches. More leaves had it but can’t make it out in that pic

Just remembered the name. Anthocyanin.
Here’s a little description;

Nutty skunk isn't wrong, and low 60s and below have shown to encourage purpling, however I always witness this to occur in a gradual progressive sense. Not randomly spotting splotching here and there. However! You seem to be past this. Anyways, good work.

Honestly, if I see that color. I think, shit man… I’m fucked.
