Curious cola leaves

[Pokenfun]

Flowering phase seems to be moving along nicely, but noticed the newest leaves on a couple of the primo-est colas are turning white on the ends. Looks sort of like pure trichs developing.

Anybody seen this before? Overall, my one lonesome Lady seems very healthy. Total rookie grow - might be getting lucky with this girl.

Is it just on the tips? Have you changed anything recently? What's the temp and humidity?

Chlorosis from being too close to the light source. I suspect you have some strong uvb wavelengths. Let me guess there are some diodes that appear as though they are not emitting visible light, these put out uvb.

I have only seen that on the tips of the buds. Learn something new everyday.

The strength of these uvb emitters might need to be adjusted should they be determined to be the cause.

Thanks for the advice friends. Looking closer at those white tips w/ a 40x glass, the white area of the leaves is actually somewhat opaque and appears to be packed w/ trichs.

Will be raising the light a couple inches, just to play it safe.

And yes, there are a few UV emitters in the LED array, but no way I know of to adjust their output. Just gonna have to roll with it.....
