Would love to even out her canopy. I could do it easy. Simply no space to get any wider. Can't even fit the entire plant in the frame. Here's what I could get and still get a decent picture. Already long past the point of being able to rotate.

Topping Day #2
Q: What do you do when your auto unexpectedly gives you more time to train before showing flowering than you thought you'd get?
A: Why, top her again, obviously!
I topped the two mains from the first topping. I also topped two side branches (for the first time), one on either side of the plant. Here's the four branches that were topped. And yes, I'm done now. Sorry for the blurple pic, the camera wouldn't focus without the added light. Lmao.

Oh nooooo! You appear to have broken the cardinal rule of Autodom, and you surely have stunted her now and consequently decreased your yield! It's supposed to be easy to grow autos and you with your antics are making it complicated. For shame... tusk tusk and please hang your head in apology for not following the established dogma of the all powerful (and easy to grow) Auto.

Light Check
I decided it was time to use the app and see how high the ppfd was at the height she has now stretched to. Yikes! She was getting hit with 1380-1400! I had nudged the light up a bit by eye earlier today, which is what prompted the check. Gotta remember a little is a lot with the dimmer on the @NextLight 420h. Also have to remember that human eyes are complete garbage when it comes to estimating ppfd.
1400 is simply too high. Thankfully I checked after only a few hours of the increase. They *might* be okay there, I have never run at 1400 before. I've burned plants with far less. But those are my best colas on the plant and I have no intention of screwing them up over a couple hundred points of ppfd. The fact that they don't yet show the slightest problem with it is a mirage as it's only been a couple hours at this level. Over two more days of this the top pistils, I suspect, would get quite crispy.
Btw - the light is barely at 50% of full power. Never ever have I run any light at this low a power level. Lmao.
So I dialed it back down so that the highest point on the plant is now getting 1250 ppfd, which is where I want it. With the light at its' current height and the tops getting 1250, that makes the ppfd on the second, 6-cola ring around 1050 and it makes the bottom ring around 750-800 depending on how tall the bud was. I'd love to get that lower ring up higher in a perfect world, but I knew this would be one of the downsides of this style of training. My "gamble" was that even the lower ring would get enough light to produce decent buds all around if the ring wasn't really too blocked from above. In a larger tent situation you kind of want at least 650-700 in your edge and corner numbers to not completely waste that space. In this little 3x3 with this big a light in it the edge and corner numbers are higher significantly than they would be in a larger tent. The lower ring buds should be just fine as they're all in light higher than that on the edge all around.
If she stretches no more we can leave it like this and just let the buds grow into the light. A couple more inches and we will be forced to raise the light.
Here's the proximity of the highest point on the plant to the light. This picture was taken with my phone anchored against the edge of the light to try and show the "real" distance. For those keeping score, that distance is exactly 9".
This is what I have left above the light. Very happy now with the decision to put the filter and fan on the floor instead of above the light or I'd have nowhere to go. As you see it here we have about four inches we can raise it. The rope will raise it one more inch before the two black plastic things come together, and if I eliminate the ropes altogether and just hook the light to the clips on the ceiling bars I get my four inches.
Hope I don't need to raise it anymore. I'd really like to leave everything now that it's all dialed in and just watch this baby go.
I hope y'all are enjoying your Friday night!!!

Don't you hate when you make that one stupid mistake?
I made my first and only mistake so far in the big tent tonight. I forgot to close the one corner of the back (smaller) door on the tent at lights out. I didn't catch it until after my nap at 8 pm. This means that for two hours there was a teensy tiny bit of ambient light getting in through that space. I'm talking a teensy amount.....the garage door was closed, the small tent door was closed, and all the lights were off. It is so dark in there under those circumstances that I almost didn't see it was still slightly open when I hit the garage at 8. Of course I closed it immediately.
I highly highly doubt that two little hours of that amount of ambient light one time in the whole grow is going to hermie the entire tent or even a plant. It's really no biggie (not that you want to do this, lol). But it's one of those things where you're like, "damn, haven't screwed up this entire grow....fuc-."
That will now gnaw at me for the next 60 days.

Lol! Thanks Felipe, I know it's not a problem, just one of those things. What if you mixed a nute mix and realized right after you fed it that you accidentally had doubled the N by mistake? (I'm sure that would never happen to you, lol) You might not worry too much if it was only once, but wouldn't you be like "damn?" That's all this is. Actually, my example here would probably be much worse than what I did! Lol.Don’t worry, Jon
What Felipe said, and
I've mis-mixed nutes and used it as an excuse to flush the soil clean!

See what I mean? In that case it obviously had some impact on you cuz it "forced your hand" to a flush you wouldn't have done otherwise, yes? Lmao. That's all it is, it's just in this case the only action I could take was to close the damn tent all the way.
I'm just determined that one of these damn days I will complete a grow start to jarred with ZERO mistakes. This is my fifth grow, it hasn't happened yet.
What is it, reach for the stars and you might get the moon?
The perfect grow...ahhhhhh!
Not a problem in perlite hempy - just mix it right and do it again. And believe me, I’ve done it again. And again once.
Or the broad side of a barn.See what I mean? In that case it obviously had some impact on you cuz it "forced your hand" to a flush you wouldn't have done otherwise, yes? Lmao. That's all it is, it's just in this case the only action I could take was to close the damn tent all the way.

Hello Jon!
Wondering are you using an IOS device and the Photone app to measure PAR?
1400Umol/m2/s is prob way too high for the autoflowers. But incase you used Photone app for the measurements - what lighting option did you use? If you’re having the fee version and using the default setting ”Inc. Regular” to measure led’s PAR, well that option skyrockets the numbers and wont be accurate.
I remember took couple measurements from my 420h Led at +20" distance dimmed to 50% and got about 800-900ppfd on the hotspot. First I had the default setting on and it gave me like plus 1500Umol/m2/s for over 12x12" area.
Looked up 420h PAR map and these should be pretty accurate values
And rest of the PAR maps are here: 420h
For over 12x12" are it provides a very even PPF. And for autoflowers you generally want to maintain about 30-40 DLI during the flowering, without additional CO2 supplementation. (+1000PPFD with 18h light cycles provides +60 DLI already)
SanLight did an interesting comparison growth with Photoperiod plants.
They tested whats the max amount of light that plants can absorb/use without making the buds to bleach.
TLDR; +40 / max 60 DLI constantly during the flowering resulted flowers to bleach.
Higher PPFD & DLI resulted in more dry mass but the quality and appearance suffer.
30-40 DLI seem to be ideal for the flowering plants.

Thanks @Verbalist. Great information. Yes, I measure with the Phototone app. Yes, I properly use the full spectrum setting and get accurate numbers for the 420h. Yes, 1400 is too high for this plant. Yes, I practically know the par charts for the light by heart as I do for any light I own.Hello Jon!

Here's the thing on the par charts - they don't give you one for a 3x3. In that size tent you can get the ppfd at plant height into the 2000s. It's really more of a 4x4 light, it just destroys a 3x3. Just the way I like it. The chart you posted and all the ones nextlight has don't cover it. You can't just take a 4x4 par map and look at what's happening in the 3x3 space on the map, it doesn't work like that. When the walls are AT 3' the map changes significantly.
One thing I have noticed about the Phototone app - other things can skew your readings too. It's useless for the outdoor rig during the daytime because the ambient sunlight mixed with the blurple light completely confuses the software. Lol. Also, there are certain LEDs that are "full spectrum" that do not register accurately in the Full Spectrum setting. A few you have to use Red/Blue despite the light being full spectrum. My good light is such a light, due to it's high red and blue peaks and relatively lower greens than many LEDs.
I've been up and down the pike with this app. I love it. Other than an Apogee I think it's the next best thing, and WAY cheaper!!

The numbers on the chart you showed are about what I have going on right now. The lower ring corresponds well to the edge numbers here, as do the hot spot numbers. Only I have those numbers in the 3x3, at 9" above the top of the plant, and with the light at approximately 50% power.
