I have a few 5 week olds and I am having continually worsening problems. Over the past couple of weeks they began drooping at night, developing brown leaf tips, and the growing medium they came in( they were clones) has white spots which are now a full fledged mold and or fungus. They have been under a 400w hps at about 12 in distance on an 18/6 schedule. These are hydroponics, so I give them one 10 min ebb and flow cycle which I just recently purged of nutrients because I thought they had a nutrient overload. This was obviously not the case because they have gotten worse using only regular water. The temp stays between 65- 79 and the humidity between 45- 60. The first picture is them at their healthiest, what you cant see are the slightly burnt leaf tips, and the second picture is the mold problem. The 3rd pic is a far view of roots and medium. The fourth picture is taken after 16 hours of light and shows the drooping compared to earlier that day.

Spray some hygrogen peroxide on the mold, that'll killl it immediatly. As for the droopiness...in soil thats means too wet or too dry, but in hydro idk. Maybe not enough oxygen to the roots???? Good luck!

I consider the drooping as if the girls were sleeping... as long as there normal when the lights come on i think your alright bro..

Even if they begin drooping after about 14 hours of light? How do I know if the roots are oxygenated enough? They are nice and thick and white out the bottom.

"How do I know if the roots are oxygenated enough?"
I have no clue how people grow in hydro. Why did you go that route if you dont know how. Aren't you supposed to have all kind of PPm meters and fancy techno equipment lol. Sorry I just wanted to kill your mold. I hate mold lol. Seriously good luck.
