Beginner's plant illness

[ant03388]

Hi Guys,
Me and a friend, 3 month ago start a crop from seed, let me explain you the setup,
We got
-150 W HPS
-400 W MH
-300 LED
-air exchanger
-Fans

We recently add the 300 W LED and at the same time we put our crop in flowering state, We are very carefull and we notice some leaf start to sag and brown spot start to appear, some leaf took a yellow coloration, some tip of leaf start to seam like burn. Due to a plumbing problem we had to move our crop in an another room for like 3 days with all the ligth and a this moment we started noticing all the illness symptom. In the temporary grow room the plant were closer to the ligth. So my question, does it have too much ligth for the plant cause we recently add the 300 W LED or is it a symptom of something else.
Here's some photo Thank You for your feedback

Just for information,
We enlarge the gap between the plant and the ligth to prevent problem seen on internet...

That plant looks fine..dont go chasing something that's not a big deal..sometimes plants need to adjust to leds..it will get used to it..also are you feeding nutes..I suggest using 2/3 less if your using nutes and leds or they tend to nute burn from my experience. .let it be..it's fine...mine have leaves with spots..yellow leaves..it's just happens..mine are under a mars 1200 and a 96 reflector..spots haven't slowed them a bit..just my opinion...happy growing..
