If you've been supplementing. Id say you od'd
They'll rust spot, from the vain outwards.
Thats what it looks like to me. :peace:
Imho
Just water. See if it improves.
Stop the calmag next feed too.
Good luck.

I've been adding 1ml to a gal of calmag is that enough to over do it? I using to water it raises ppm to 50-80

The plants dont look bad mate, at all.
Id cut the calmag.
After a few waterings / feeds. If its getting worse, and spreading. Up your dose.
Its a big room dude. Play it safe.
They wont drop dead from deficiency.
But if you up your dose and fry them.........
Go the safe route:peace:
Rule out toxicity first.
Make sure ph is in check too.

Go from there.
Good luck.

Maybe. Good thought as well.
Seems unlikely though. The fan in the first pick looks pretty crisp, and dry. Its curling up as well.
Worth checking though definitely :peace:

Then grabbed one of my books .

I gotta go with LS .

If the humidity is outta whack.
Tbh, i think you could be right.
Imho. Its the dryness, and crisp leaf that tells me no. Almost looks like a fried rams horn.

Do you think checking humidity,
Cutting calmag
Checking ph

Is a good plan forward??

I’m just not seeing any other sign of lockout or dif.
If it was a lock out Or dif. There would be other signs.

With out being there and knowing all the variables, alls we can do is guess.
I like to come in n look at these threads for these discussions to keep me on my toes .

Thing is too. Imho
If its toxicity, its happening during translocation.
That would explain, the symptoms spreading from the vain.
Deficiency i've found to come in from the new growth, and edges of the fans.
If its toxicity the plant dumps it where it needs it least. Which is usually the ends of the fans.

Imho.
You raise a very good point and we shoulnt rule it out.
OP should definitely have it in mind, if it keeps spreading.

Ok. Didn't realize you could get leaf septoria indoors. Humidity Is between 50-60% day and night temps are reasonable around 80 at the tops. Reason I thought it might be calcium excess is growilla bud has 9% calcium but it is organic slow release

Yeah 9% is huge man.
Just do the steps.
Rule out an excess first.
Im sus on the calcium too mate.
I think if, you think you did. Then you probably did.
But check it all.
Be thorough :peace:

It is almost ALWAYS an excess of something...leading to a lockout of something else.
Don't put shit in your soil unless the plants demand it. New soil in a pot will perform poorly but will improve over time if you keep on inoculating it with compost or vermicompost tea

Not bad.
IMHO
Might be worth a little npk.
Something high in nitrogen.
Just a light feed though. Only a little.
Only if you havnt yet too.
