Long time lurker in need of help

TSP,
I agree that what the article is talking about is unrelated to light burn. The article even says so.

And I don't know...this doesn't seem to be anything new. A good White Widow matured properly will appear white like that. (hence the name)

Maybe your plant is displaying that white-on-white, time will tell.

you can gently pull the tip of the bud open. if it's still green and healthy looking under the white, that's a snowcap, if it's dried out and crusty, thats a burnt tip

Damn, I learned from you more in two comments than I did from the entire YouTube, I appreciate it.

I didn't want to fuck with it too much, but it looks like a burnt tip.

hey, i don't mind sharing the results of all the mistakes i've made. because that's how i've learned most of what i've learned. fucking things up, then figuring out what i did, and how not to do it anymore.....

Show me the man who claims to never make a mistake and I'll show you a man who not only fails how to recognize mistakes, but how to learn from them too.

So true.

By the way, talking about recognizing mistakes: so, I mentioned before I used a spreadsheet to track the grow, recording everything I thought to be important. I also added a chart with ambient temperature, leaf temperature, RH and reservoir temperature, because why not. I realized today, when I looked at said chart, that I was an idiot, because the problem was staring me in the face, so to speak. I learned from this guy

that using leaf temperature was a fairly adequate way of checking how far your lights should be from the canopy. He says if your leaves are warmer than your ambient temperature, the lights are too close. Take a look at my chart:



The ambient and leaf temperatures are pretty much the same until 10/5, when all of a sudden there's a sizable gap between the two. I noticed the yellowing the next day, but totally missed the connection. A closer look:



So, yeah, I've proven again that I tend to be the dumbest when I think I'm being oh so clever...
