Accidentally Light Bleaching Your Grow

Have any of you accidentally bleached your grow with too much light? I haven't but I was wondering what severity of light causes the bleaching (so I can avoid it).

 

bleaching would come from over watering, and lack of nutrition..

 

Ok, cool - so the light really isn't a factor at all?

 

I don't know much about growing, but I always thought pot plans need a shit ton of light in order to be successful....

 

light to close to the tops can cause bleaching, but this would be different because it would just get crispy and die..

lack of light will cause the green to fade also... dark rooming.

MH lighting will get the plant greener- along with some good food ..
HPS light will can cause some yellowing, but this is natural as the plant finishes flowering cycle..

 

It's too bad it loses it's potency because it actually looks really cool:
