Light bleaching with LED's, fake news or naw?

One website says it's bad, an article reposted by an led company says it's great and you get an f-ton of tricombs.

I've looked in the past with my zorb, there seemed to be more trics to me.

Buds. Not fattening

Hello there!
Light bleach / light stress, light burns are the terms used for this family of issues, no need to worry too much on that, just move your lights away. The affected buds that turned white often mistaken as white cannabis, starts to loose potency or have no potency depends on the severity. So this trichomes info sounds strange.

A few things to keep a look on are your temps too, to make sure you don’t have heat stress...

There is a technique i had tried before called Back Building, you can have a look on that, basically is a HST technique that makes the plant focus the energy also in the lower buds, have a look on the timing is made also so you do not compromise the growth since you are making an auto.

Happy growing, cheers!

LED burn is real, my green crack suffered some LED burn. She turned out OK. Loose airy buds, but still gets me high as hell.

I’m not sure about light bleaching but I have seen light burning from lights especially with leds as they are far more focused than other lighting types and because led manufacturers always tell people to put them much closer than they ever should be. You should be fine to put them under the led though you may need to raise the light to prevent burning. As for the added tricomes that’s a 50/50 argument that I personally haven’t seen any unbiased research on

There's a reason it's called light "stress". The affected buds loose some potency, how much? I could not tell since that has never happened to me.

well, at the beginning you had some issues with nitrogen, a nitrogen deficiency, due to the yellow leaves and when you said that leaves fell of by their own. Don't know if you have done something about it, but in some cases people make the mistake to feed them with high levels of nitrogen after some issues and this can be to late if plants are entering the flowering phase, when they need lower levels of nitrogen, causing a nitrogen toxicity. It is normal some leaves turn yellow when harvest time comes, but thats not the case here, you need a few more weeks I think. Don't know if leds burn the plants that easy, but that's not good to have the canopy touching the lights in any case... So, my bet goes to the nitrogen all the way, cause too much nitrogen can actually prevent proper budding, and can reduce the overall taste and smell of the plants. Probably they got to much nitrogen, and buds doesn't fattening like they should...
