Radiant heat could be another possibility.

I can keep my ambient temps at 75, but still have radiant heat issues if I don't have my fans blowing between canopy tops and bottom of hood.

Yep. The biggest surprise for me was when I held the Lighting Passport under the 860W CDM Allstart lamp and saw that the single highest, broadest peak was infrared.

I'm gonna be super honest. I'm an awesome grower. When it comes to deficiencies and light spectrum values from one bulb to another, honestly I haven't done my homework. 4 yrs banging out superb runs, but never bothered to read up on those 2 things. I've never had a deficiency yet. At least not one that wasn't remedied by either a normal watering or feeding.

I just did my flower room work. For day 24 from flip, these girls are looking great. Only running 1000ppm co2 on fuzzy logic. Ambient temps are 81*. Nice flowers, super frosty (I do use terminator).

BUT I've noticed on 3 plants out of 21 k may be more), but 1 or 2 bud sites white hairs look like their Turing brown and receding already. Way too early for that shit.

SO, I'm not really a betting man, but I believe it may be either due to my hood reflecting the light just a certain way. I was thinking it may be too much uva/uvb, but if so, most if not all buds would have funky hairs thing happening.

Early hair turning is one thing that I have surely seen under the LEC315.

I checked the trichs to be sure.

The effect seems to vary across breeds.

These are day 24 from flip. On 1 to 2 buds at most on 2 to 3 plants.

(not seeing the images...)

Didn't post any

Picture the white hairs receding ever so slightly, and Turing like they would at sat week 6 or so. It's only on a couple on 2 plants or so.

Ah, I see. :0)

I'm working in my veg room now. Tons to do, then head home to get my boys 3rd birthday stuff set up. I'll try and get a few pics tomorrow. Turning on my 3rd 315 cmh in veg tonight.

Michigan....sorry to not have taken them time then and there.....but those white
buds are just crazy. The only thing that I have seen make bud that white was a mold.
(I learned not to spray down giant tops...dumb move)

That cannot be bleaching obviously and the only other dark-stimulated loss of color
that I have seen is the yellowing of leaf-loss.

So, I was quiet because nothing helpful came to mind. :0)

I didn't mean to come off impatient. I really appreciate you checking it out.

It's the lamp though. It does not have enough penetration to get through the 600HPS grown plant. These things are thick with buds and leaves

The half plant has greened almost all the way back up under the HPS already.

It must be a very sensitive sativa genetic. And I stressed her out bad.

The buds however look and smell fantastic. Maybe the lowers will get good too.

I hate to suggest this but possible pollination?

I don't believe so. I am running 6 new strains I've yet to flower. 2 are from seed, rest were clones from a buddy. I thoroughly inspect those daily. Top to bottom for nanners. I am a very accomplished nanner hunter. Went thru hell for 4 runs with those he-bishes yrs ago. And I used to do paint inspections on 80k to 2.5 million $ paint jobs and restorations. I've got an eagle eye. Knock on wood.

I find them when scanning photos I take of my plants.

Not eagle eye....kinda funny....like, what what what?!?!

Well you got that covered. And the attention to detail sure shows in your grow.

I did say I hated to suggest it. But it is the first sign. So I had to just in case.

Just to update.

The lower half of the BW x BLT with the white buds and foxtails under the new 315lec.

It has already greened mostly up and also finished turning many pistils dark to finish. The buds are actually filling in and getting denser back under the Super HPS 600w.



So what height are you all keeping the 315 above the canopy for flowering?

I have a bud that is now at 16" and shows no stress now that I have my circulation fans set up better. And I read that is where the par and footprint is maxed out. I would say 2.5 feet square of good light from my reflector at that distance. As a guess without a real par meter of course.

Mine are farther than that. I also pig out and have plants
way beyond that footprint too....but they all mature nicely.
(not too worried about yield)

Cool thanks. I keep my 600's beyond 20". Even 22"-24" for ripening. But I always maintain the proper footprint for my lights. The plants can not grow to their full potential in many other ways than just yield without enough light. It has been known for quite some time now that the full usable light at the proper intensity develops more cannabanoids and terpenes as well as a bigger plant with a larger bloom.

I think it all goes together. I don't get this "I don't worry about yield" mentality. I don't worry about it either. I keep good light distance. I stress on only feeding exactly what they need individually each time I water and not water the ones that don't need any and that seems to make the most difference in quality. And working the lights better.

And the better I do these things with each next plant I clone or germinate the more I seem to get and the better the high and terpenes are.

I agree you can end up with high yield from too much light and heavy nutes too but that hurts quality.

Nice!

May I ask your light height and how far apart?

All ran in a closed loop with 70/30 butane/propane mix. Winterized with distilled everclear and Büchner funnel then purged at 100 degrees for 96 hours after recollecting majority of alcohol in a rotor evaporator.

All grown under 315s. My yields on oil returns went up a standard 2-3% across all strains compared to 600w HPS.
