Bug or nutrient problem? (Pics)

Hello everyone
So, this is my first grow. I'm growing 2 White Cookies (They are 2 weeks old) in a sort of homemade indoor. It works fine I guess. Tº and humidity are pretty stable.
Im using a light soil mix: Coco coir, peat and perlite
They are under a 105w CFL (600 equivalent) + 40w CFL (120 equivalent), this last one was recently added 5 days ago, plants seem to like it.

I screwed up a little bit. I added root nutrients within the first week. I read it was Ok as long as it was a very small amount. Both of my plants got nutrient burn (First true leaves had yellow tips), but nothing really serious (at first).
Days passed after the nutrient problem and the plants seemed ok, growing and with no signs of deterioration on the leaves. I noticed one of my plants grew exponentially tho.
I waited for my soil to be dry, and started watering again. But this is when the burns started spreading. I used only water. Tap water which has a fairly good pH level (6.5-6.8.), but the burns got worse.
I read many forums, consulted with some growers and everywhere I went, I got the same answer: Flush it. But because of how young my plants are, it was a risk.

I finally did Flush them a couple of days ago, and the nutrient burn problem is gone as far as I'm concerned.

__TL;DR__:
But here's my actual problem right now. I think one of my plants may have a bug issue.
As shown in the pictures, the leaves have some dark spots/stains. Which were not there before the Flush.
These leaves were the ones that showed the nutrient burns at first. One of them looks "broken", that's because I touched the leaf to see if it was getting crispy... clearly it was. (I apologize, it's my first grow)
Now, I believe these stains are spreading, and I'm not really sure what they are. The rest of the plant doesn't seem to be affected yet.
What do you think it may be? And how can i fix it?

Thank you all!

not a bug issue. idk what the spots are. could be spores but I'm not sure. def burn on the leaf tips. new growth looks good so you should be encouraged.
