Sweet Skunk Auto ~ Sweet Seeds

I use both spectrums the whole time, from seedling to harvest and truly believe it to be superior to only using the veg light on its own during the vegetative cycle. Hope this helps,........ Organoman.

It actually is a little bit of both. The tips are slightly burned as you stated, but you can also see some leaf cupping which is a sign of light/heat stress. I would just back off of both a bit, take the light to about 24"-30" inches above the canopy and go a little lighter with the dosage of nutrients.

Still early in flower and those are some big plants with a lot of budsites. Nothing to worry about mate, Everything looks great.
