What in the world are these red colored dots? (Please don't be leaf septoria!)

Kind of freaked me out when I saw these. Just want to make sure it is nute-related and not some disease.

I am pretty sure I had aphids, but got rid of them the way I found online (Bayer advanced-still @ least 2 months of veg) which I used 3 days ago @ last watering & just found these today.

Accompanied by purple stems & part of the stalk. Transplanted 2 weeks ago to R/O soil.

So I am beginning to think it is more nute-related because I noticed it is only on that one strain inparticular so far. To me it looks like they have nute issues in general (partially caused by ph issues) But I am still new to this.

What do you all think?

You just started them on cal/mag a couple weeks ago, correct? Sorry, trying to remember.

Yes, exactly two weeks today. Good memory. Unfortunately i've been slacking with them (as far as reading PH recently) been watering from the drain trays.
So I guess actually three weeks since transplanting.

If it is not a disease I am not too worried about it & would not have posted, I just wanted to make sure I didn't need to throw that plant out before it effected the rest.
I googled red dots on leaves & saw pictures of "leaf septoria" that looked pretty similar so I started to freak out lol.

I think they need to be transplanted, growth took off after taking your suggestion on cal/mag.

To be honest...I just make sure what's going into plants is between 6.3-7.2 roughly(im in soiless)...and learned a trick from another member to deliberately move it a cpl points up or down too make sure plant gets everything it needs. I don't test runoff....started when I first started growing but got to a point where was not needed anymore..and it was far too confusing and frustrating......sort of felt like I was "micro managing myself"....lol....:)

PS....Don't water from drain trays ever......do not put runoff water through your plants...Good luck! :)

Thank you all for letting me know it is not a disease. Any idea what it is? I am starting to look it up now. Only thing remotely similar I could find in my book "How to Save a Marijuana Garden" is a manganese deficiency or maybe phosphorous (but that one seemed highly unlikely)

It is spreading fast on those two strains, any ideas?

Heyy, well that is good to know, I appreciate it :). That's something I will remember for a long time for sure. Haha it definitely can take some time. I have only been doing it every once in a while. Their Ph's were around 5.8-6.1 two weeks ago. They still aren't all above 6.5 just yet, & been watering with 6.8-7.0 ph. Crazy it's taking so long to readjust.

That is really good to know. I ask because I want to learn; Why do you say don't water from the drain trays?

I've only done it once with these in-particular plants, b/c it was convenient on a busy day.
