Firstly: please note the question mark in the thread title.
This is my experience and entirely anecdotal and of course informed comments are solicited.
I recently hung a GeekBeast 650 pro in my tent. I confess I am such a stoner that I put the thing together and didn't notice or didn't remember seeing the switches for UV and IR. At the time I thought all the GeekBeast LEDs were controlled by wifi or bluetooth (I hate bluetooth). So I hung the beast in my tent in an orientation that placed the wiring close to the end wall so I could easily mount the driver exotent. However this made the UV and IR switches hidden against the far wall of the tent.
The plants were in about the third week of veg when I did this. In a few days I noticed that many of the fan leaves has liquid on the surface.
a week later I saw the effects of light burn all over my nineteen seed-born lovelies. I was running the beast at one hundred percent brightness. So I thought that was the problem. I turned it down to 60 to 70%. Still light burn. I finally discovered the hidden switches and saw that the UV was on 16hrs a day.
Long and short of it: out of 19 plants, 4 of them turned out female. All of the females were on one edge of the light were the brightness was the lowest.
In all my decades of growing from seed, I have never seen a ratio of m/f like this. In fact I never had less than about 60% females and most of the time it was better. Now before anyone points it out: I am well aware that 19 plants are virtually statistically insignificant BUT the fact that the four females were all in the least bright area of the light, all of them, along the one corner and edge, makes me very suspicious that the burn caused by UV during veg somehow stimulated male expression.
