Can’t go wrong with some gg4.
Is this your favorite strain? What features of it attract you more.

The increased K has helped with burning, but look at the edge roll. They are really struggling to hold in to moisture. While one isolated pic suggests calcium uptake may now be effected.
I have noticed another change in your grows over time. This one is stood in the middle of a large room, not against a wall. With lots of defoliation and the wall fans, the RH under your canopy must be lots lower. With greater illumination down there also.
I have found that air movement down there is good, but not the same volume of air exchange as above. When I really did my best to freshen it up down there, Nothing good came of it. I saw gains when I changed back to a more humid arrangement. Indoors or out, my plants do better when bunched. Though my meters don't suggest why. Just this week I filled a screen, and the instant bolt for the sky followed as usual.
If this starts you thinking, then some pallet wrap could be run around to judge if it's useful.

If this were the case, wouldnt the plants towards the middle all be doing better where there is less airflow? Because thats not the case. The roll is also not consistent, only on the tops of some strains. I also bring my rh down as the cycle progresses. Maybe i should raise it? I dunno, ive got some chunkers in there and botrytis is a real threat.

Does less airflow translate to less CO2?
Not necessarily, i have 10 wall mounted 18in fans as well as floor fans running. Also the blower is constantly moving air. My sensor is placed at canopy height in the middle of the room, co2 is pretty damn consistent throughout.
No she is not. I like making new varieties using Hazes/Sativas to add back those elusive chemotypes/terpenes I love. Ive not found a long term keeper in any hazes or haze hybrids yet. Ive found it more difficult to breed for the chemotypes I want.. Haze polys are were im finding most of the unique terps, I think they are the key that will unlock any potential for these chemotypes to show up. . Its a very time consuming effort. These longer flowering genetics are harder to keep healthy in every way.

The middle would likely be better, if there is less airflow. It looks very open with little to baffle air movement, but you will know better.
Are they thicker as well as rolling? I forget you ramp up the power for a number of weeks. Was there any relationship there? These leaves really look like a HID grow, where they are really trying to protect themselves. I see a number of blue LEDs in your lights, but I'm just making an observation. Maybe down the road you might cover them, if this rolling troubles you. Right now I'm thinking water loss, rather than avoidance. It kinda depends how leathery they are.
High CA or low res temps can slow water movements. Or just not watering enough. I doubt it's that though.
What is the temp/rh? I have sacrificed yield to avoid it being taken by rot. This might just be something you have to accept. I might look at reducing just one light though, to see if the answer can be found. If they are protecting themselves, then they may do better with less light. Or just less blue.
Cool, breeding new strains is something that takes a lot of effort, and we hope you succeed in cultivating the high-quality strains you want.

This cultivar get so much love. Is it cut only?
It is available in seed form and from clone from Beleaf

From Simon @SeriousSeeds
Yes the fem and reg seeds are different because they have a different father. We do not sell self crosses at all. All seeds have 2 parents, and fem seeds therefore have a different father than reg. seeds. The mom is always the same in fem or reg seeds.
We try to find a female 'father'plant which resembles the outcome of the reg. seeds as much as possible. Sometimes this doesn't work out.

Looking again (before getting stoned) I see the curled edges are all coloured from carotinoids. This is light avoidance, seen more often outdoors, than in. Suggesting it's the blue light interfering with leaf function.

so, the first pic shows crooked8's light fixtures. we can clearly see two types of "white" light diodes, warm white 3000k and cool white 5000k plus the the 660nm dark red. i'm not sure what the blue diodes are, but possibly UV. maybe crooked8 can tell us.
and the ratio of warm white to cool white is 2/1 which also seems to be the recipe most led manufacturers are using.
the second one shows what the 3000k and 5000k spectral distribution looks like. the third one shows 3000k warm white plus 660nm diodes.
all approximate but looking at these i don't see that he has enough blue light to cause the leaf taco that he shows in some pics because his blue/red ratio is what we should be looking at overall. his lights are typical for the industry. most led manufacturers use this light recipe.
also, some of crooked8's plants show the taco and some don't which has me wondering whether they are in the same room or, if they are not, do they have the same temperature and rh%.
because if they are in the same room or an identical one with the same parameters of temperature and rh% it would tend to make me believe that some strains are more prone to display the taco than others.

Blue diodes are UV yes. Agrobar (I assume this is the 720 from his diary title) doesn't say what they use but LG UV 395 if I had to guess based on the spectrum.

next, i went to the dimlux site to study how their lights are made and while there i found interactive vpd charts. they allow the grower to compare the differences in vpd based on room temperature and rh% but also leaf temperature. it is the first vpd chart i've seen that takes into account leaf temperature as well.
i could not get the interactive chart to download so i copied them all to make the comparison easier.
the charts show the differences in vpd between room temperature and leaf temperature plus rh%.
they are labeled but i put them in order as well. they are for 0%, -!%, -2%, -3%, -4%, and -5%.
i think crooked8's taco leaves are vpd related and strain specific.

i immediately went to my little 2-plant experimental grow which is in late veg. i had a room temperature of 84f and top leaf temperature of 82f.
The corresponding chart for a minus-two F condition shows that my ideal vpd is .91 to 1.14 which is 70%-65% RH respectively.
my room is 56% so i'm off some but there's not a fucking thing i can do about it in this old, leaky house.
i want a sealed room again so i can play god to my plants. i will be there soon. can't wait!
