Is the red spectrum bad for young plants?
My new plants are HATING my new t8 leds!!!!

Just read this,interesting...
The Effects of Far Red Light in Vegetation
If you’re getting stretch in the vegetation stage, too much far red could be the culprit.
Because far-red makes your plants think they’re in the shade, they keep reaching upwards in search of the sun. Their leaves grow longer and wider and their stems elongate. The unhappy result is a long and lanky plant that’s too weak to hold up the healthy flowers you’re hoping to cultivate.

I'm just learning here too, but it might be the proportion of red to blue, or red to green, etc. So you may want some red but not a majority of red. It probably depends a little on the plant too. Like equatorial sativas may be even worse under higher proportion of red for young plants, which is just my guess.

Maybe these lights are not really full spectrum?maybe more on the pink/red side?

Interesting. Has me thinking how plants evolve like further off from equator spring would actually shift light more to red side I think all other things being equal, but blue would be increasing every day. But all else is not equal, because rain clouds in spring diffuse the light color and I can only say it seems more gray or white which seems would be a flat spectrum graph. And fall would be increasing red spectrum every day. I think on equator would be flat spectrum any time of year and just less light during rainy season which I don't know if that is during veg or flower? Sense?

Yes, I think light makers are very liberal with the term full spectrum. And leds dont seem full at all. They just combine a few color lights which the color is actually spread a bit around a wavelength and they kind of overlap to create a wider spectrum but full would be flat all the way across if you ask me. And the invisible wavelengths probably do matter as well, contributing to the heat of the leaf surface and such.
