Is this septoria??

[Snurge09]

Hey everyone hope your all well today.

I have a current grow going with 4 ladies and over the past 48hrs ish I've noticed a little spotting turning up on one plant and now I can see it on another plant, at first I thought it was lack of light on the runt of the 4 but now I have them on my biggest lady, do I need to worry? Could this be septoria? Heat stress? Lack of air flow etc ? I can grab more pics if needs be thanks in advance for your help.

Looks like CalMag deficiency or lockout of calmag due to medium ph
I've not heard of a case of septoria in about a decade here, so it's probably not that. ^_^

It happens quite a lot, especially with LEDS.

She seems, I have 4 of the same strain (purple haze auto) all treated the same feed wise, organic fertiliser PH'd and was ok and ppm/ec were all good in my feeds, all 4 are totally different to, 2 little shrubs and two larger ladies, taller ladies are starting to get sticky and we've turned the corner that's what made me think of septoria, will check my soil pH and run off again, on the calmag I've never had to use it if I'm honest and gave it away haha
