White top... Anyone seen this before?

I agree light burn at the top of the Plant, but that's the least of your problems. It looks like you have to much Nitrogen, the leaves are too green and a possible Magnesium deficiency, the leaf veins are necrotic. Your trichromes are decapitated. That white trichrome bundle at the top looks wicked. Start at square (1) test soil Ph, soil temp, is the soil wet, is the plant taking up water. Look into Plant Deficiencies Charts. It looks like your not far from harvest, put this grow under your belt. Try and find out whats going wrong so you can avoid it in your next grow. Research the Strains your growing, some Strains are sensitive.

Yeah mate. Its a RDWC and there's almost 0 nitrogen in the solution. She's almost done alright, this strain goes purple at the end. You must have great eye sight to see the trichomes. I'll show you a picture of the leaves not getting light later on and you'll see its quite healthy. Appreciate the detailed response though.

@Blent- You're right man. I meant to say pistils... I'm pretty baked, sorry about that. My Bad. Honestly I have to say she is one Wicked looking Plant. Sorta sad she can't be frozen in time, and put on display. I apologize for speaking incorrectly.

3 people told you it's bleached. It's bleached. Temperature has NOTHING to do with it. I would elaborate, but you know everything there is to know apparently. So you must know that this is a CLASSIC negative effect of LED.
LOL OK bud... You alright? I'm not claiming to know everything... It does look like a bleached tip alright. Well done, do you want a like and a gold star

Hmm
Well let’s just say the op knows it isn’t bleached like he says
Do you think it is genetics or something?
Check out this article I found that was very interesting. I think this is what’s happened.

Nope. It is a spectrum issue(op should thank you for this reply). HPS when too close the plant doesn't give the proper spectrum. Same thing with LED. Sometimes they just don't deliver. For various reasons. It's still relatively new technology and most LED's actually don't even possess proper UV. We still have very far to go in the LED realm.

The FACT is, the very upmost tip of the plant is where the bleaching is. The plant didn't just run out of chlorophyll for it's very most important part. It had a problem producing it. The fact that there is no other part of the plant that is bleached, or yellowing, also indicates it is not a deficiency.

There are multiple pages written about it on this site, as well as others.

IT IS 100% LIGHT BLEACH/BURN.
