WW-- better, thanks! OK, that color break is something we see pretty often, if it started from first true leaves,... sometimes it clears, or not,... sometimes the plant grows fine,.. or not,...

.. it just varies! ....no idea what's behind this color break, but it's inherent in the seeds,... all you can do is grow her out and see,... I do see the heat/light stress damage,... I do not see any signs of vermins, so that's good!
What lights are you using, distance to plants, T and RH%..? --- Oh, I see them,... they look OK, and the lights were for sure too close! No more pointless spraying for mites,....
... last pics: those spots might be early Ca defc. starting, hard to say for sure just yet,... get Ca-Mg going, and start raising the nute conc. a bit at a time,... bigger plants , bigger demands!..
Arthur, thank you for helping with solid advise mate!
