My plant is 27 days old and I fed it yesterday for the first time. The nute solution was measuring at around 0.88EC. The runoff measured at 0.13EC. This morning it started developing these weird spots. The ones I'm referring to are the ones on the left and right leaf not the one in the middle. I had a deficiency a week or so ago and managed to fix it. Did I maybe under feed the my plant and it needs more nutes or is it something else?

I'm confused if this was the first time you fed your plant how did you correct the deficiency last week?
Regarding the new spots, did you get the leaf wet when watering?

I think the deficiency came from a lockout. went to water it on schedule last week and the first set of leaves(the single serrated ones) were starting to yellow so I decided to test runoff ph and it was at 4.9. So I flushed it until I got it up to around 6.1. At that time I have never fed the plant. I was only giving it bottled water ph'ed at around 6.5. For the side leaves, I think I might have accidentally wet the leaves during feeding if not completely submerged them in the solution by mistake. I can't remember if I did for sure though.

I would agree with @myke and would add that you could not have possibly had lockout (assuming that's not home made soil) before you fed them anything. Now they are going to be hungry as you flushed nutes that may have been in the soil so they will only have whatever was left after flushing and anything you put in.
Be careful, over caring is a real issue when growing.. I have killed a few plants doing what I thought they should need.
I would also ask to see a full plant picture.

Im not sure whats going on with this one plant specifically. After I flushed it with bottled water at an ec of 0.13 due that supposed lockout, I left it to dry for 6 days and never touched it. When I fed for the first time yesterday, I checked the runoff and ph was back to 5 and ec was about 2.6 so I really dont understand what's going on with this one. I have another plant and I give it the exact same as the one I'm having trouble with and its doing fine. I added some pics of the full plant

5 days seems like a long time for that tiny pot.
I think so too but it takes a while for it to dry out. I'm growing outdoors and only get about 5-6 hrs of direct sunlight per day. Its an autoflower btw. And its already in pre flowering

To make it simple for ya, feed at a low EC to runoff every time.No guessing this way,old food gets flushed out new food goes in.
Or do a feed ,water,water type thing with runoff when you feed.
Quit testing runoff ph it means nothing and will have chasing your tail.
Good luck.

Honestly seeing the full picture it looks healthy imo.
yeah it looks healthy apart from the first 2 sets of leaves at the bottom. I'll monitor it for the next few days and see if deficiencies progresses

Old growth doesn't last forever, top/new growth will really show how healthy the plant is.
The top looks totally different from the lowers.
