Does this look like Alternaria?

Hey guys first time posting in a forum, I’m a newbie and I’ve only got 3 small harvests under my belt. None of which have been great but hey that’s all apart of the process. (At least I keep telling myself that) I pulled this plant out of my grow tent as soon as it started showing signs that looked like Alternaria to my noob ass eyes. The plant has been growing great but I’m determined to finally see a flowering stage all the way through so this scared me enough to bring it outside and away from the other plants. Spider mites waged an all out war on my last harvest so I’m just terrified of something else ruining my healthy plants. What do you all think? Thanks!

Strain, grow media, nutrients, feed/water sched, ph, RH, temps, lights? More info is better.
 
I don’t know what strain it is as I can’t remember I’m new to using this soil but it appears that I may have been under watering from all the forum research I’ve been doing. I usually pretty dense soil so using coco coir soil mix is a new ball game and again I’m still a noob.

light: ES180 V2 full strength, about 18 inches above the plants

Thanks for taking a look!

Coco needs watered/fed much more frequently than soil. Are you measuring ph and ppm/EC?
 
PH yes PPM no and I don't know what EC means.

They are outside because I'm afraid if they do have Alternaria then it will infect my healthy plants and it's summer time so if it ends up being okay then I could potentially re introduce it to my tent once I'm sure it's healthy.

EC is electrical conductivity. PPM from a TDS meter is derived from the EC. If you're feeding by the feed schedule on those bottles, you should be good.***unless you're using really hard water*** I use same GH and CalMag+.
