First time scrog...is this girl ready to be flipped?

[HomegrownOhighO]

Hello All,
Here we have some Humboldt Blueberry Muffin genetics. This is my first time scrogging. Everything has been great thus far, fingers crossed. She is roughly a month and a half in veg. I did some LST at early veg to manipulate the plant in the direction I wanted the plant to grow. I only topped once because the main cola was stem was starting to get extremely thick, and I did not want any breakage once the plant reached the trellis with future tucking. My question to the community, is she ready to flip or do I need to veg a few more weeks to fill the trellis? Below is all equipment and metrics of the current grow.

Vivosun 3x3 w/200W Winged Full Spectrum LED currently at 20" from canopy top at 450ppfd on 58% intensity
15 gallon fabric pot with Gaia Green living soil
Dry amending with Gaia Green @ a 70/30 ratio of All purpose 4-4-4 and Bloom 2-8-4
Gaia Green Basalt for Cal Mag needs
Watering 1.25 gallons pHed to 6.3 is every 6-7 days, I use spring water from a local natural spring (my plants love this water)
Supercharge every other watering
Current conditions held @ 1.1-1.2 Vpd lights on
.9 @ lights off
Lights on at 74F/58%rh
Lights of at 69F/60%rh

I think that's everything, lmk if anyone needs any other metrics. This is the current pic from my in tent camera. However, I can post some more current up close pics later.

Flip it now and it will still fill the trellis. The first two weeks of 12/12 you will continue to tuck like a madman. Then she can go vertical the rest of the way.

I do not have experience with that strain and would research expected stretch and base flip on this input.
I do see something that stands out in your specs listed. 200w is at the low end for finishing a photo based on 9 square feet.

Yeah, I would like more wattage but that's what I have. This is my 6th run and those all finished fine. I've actually had to reduce intensity or raise light due to light stress in the past.

You can flower fine at 500 ppfd. In my opinion, the quality is better with lower light. The more light you have means you must have more feed/water/temp/humidity. Everything needs to be balanced.

And like GrownSince95 says, flipping now will allow you to fill the screen during the first 7-10 days of flower stretch.

Yeah, I agree about the lighting. Balance is key.
Thanks for the advice. Sounding like it's time to flip her! I'm excited.

I plan to do some defoliation of the middle section to allow more light penetration and air flow. However, should I wait to lollipop everything under the trellis that doesn't make it to the canopy until after the flip and stretch occurs?

Most folks lolly 3rd week of stretch.
I would not do both at the same time but that's just me. Some guys know their strains so well they pick off the whole grow as needed and some do mass defols a few times a grow.
Seems strain specific.
Seems dependant on how good your grow bounces back.

So, in the past I would do mass defoliation but with this grow it's been on an as needed basis for air flow and revealing bud sites. I was mainly unsure on the lollipoping before or after the stretch. I thought about reaching out to Humboldt to see if they could offer any advice or strain specific tendencies. Hell, couldn't hurt and they may have some advantageous advice on the Blueberry Muffin strain. Thanks.

Personally, I don't defoliate anything until after stretch is over and the tops crown. I do remove leaves that overlap each other and cause water to form on the bottom leaf, but VERY few. It causes stress during the time that the plant is switching hormones

If any fan leaves are blocking flower site, I tuck them under rather than defoliating. After stretch I defoliate only to improve efficiency. (air flow, light penetration, etc)

That is great advice, thank you!

 

[HomegrownOhighO]

Well, I was getting ready to flip and noticed what I believe is nutrient burn or maybe light burn. There is some odd discoloration on the tops.
I have posted pics below. I know she looks underwatered. The pics were an hour before lights off and she starts to get sleepy a few hours before lights out every night, like clock work. Anyway, let me know what everyone thinks...it could be a deficiency for all I know. Thanks everyone!
