Thank you!

Thank's a lot! As much as I dislike the 4 plant limit that's so common in legal states and medical programs, it is the perfect number to fill out a 4x4 tent. It's just hard when you want to do some breeding.You seem a likeable character mate , lovely old school selections with an efficient and tidy canopy . They are bubbling away nicely. 4 plants is perfect for a 1.2 = nice and compact.

Hears a link on that fold 8…..this guy does the work so we don’t have to…. All his tests are done with an apogee quantum meter…and now with the new e par that detects far red

I meant to mention this earlier in this journal, but I did receive my FC-6500 and decided to just finish off this grow with the Fold-8, since it is already a month into flowering. I feel like I'll be able to do the FC-6500 justice by running it all the way through starting with my next grow. I've been super happy with the Fold-8 in every respect so far, and as Buddernugs mentioned, it has an incredible par map in a 4x4 at 80%, which is what my plants are under now. I'd like to thank @MarsHydrofactory for the FC-6500 contest once again, and I can't wait to show off this light once my current plants finish up!

I'll reserve judgement until harvest, but I feel like my grow was further along at this point during my last grow when I used fewer primary bud sites. After this post I'll show a few comparison pics. Really my goal for my last two grows was to nail down a perfect # of bud sites per plant for yield. I'm thinking that over 20 per plant is a bit crowded, 8 is too few, colas get too big, so for my next grow, I'll mainline to an even 16 each. Anyway, plants are still happy, but I have some concern that the early browning in the white widow might have spread to the plant next to it, and since they are in the back, I may have missed some intersex traits. I always get nervous at this stage of bloom though, so it's probably fine and I'll just ride it out.
Old Red Sour:
Blue D #5, smelling so good!
White Widow, strange little plant that reeks of peach:
Petrol Skunk:
Thanks for stopping by!

Okay, so, here is the same Petrol Skunk clone on July 13 last year:
And here it is on Aug 2:
For comparison sake, my plants will reach the equivalent time on the 13th of Jan. So they have 9 days to get there. It's possible, but there are a few differences in my current grow. This last grow was weird....I threw some coots mix in the same pots because that's all I had at the time (was planning on a 4x4 bed but decided against it, and didn't have any coco on hand.) Then I started getting crazy deficiencies when the mix was used up in early flower, so I started feeding Maxibloom. Also, I kept the lights closer (to the point of burning some tops). I feel like the # of tops is having the biggest impact, and there is definitely a sweet spot to be found for a given space there.

Do u remember which flowering week it was going on that july 13 pic? Pic from August looks super nice! Im pretty much in same situation trying to find out which amount of tops is perfect. Now there is about 12 in 6 plants, next one will be mainlined 16 and same 6 plants. My space is 3x5.

So, last time, my yield for that 8 cola plant was the same as my two other plants that had around 16 colas, problem is, they were different strains so not a great comparison. I ended up losing half the colas on the 8 cola plant due to bud rot-they were just too big and dense. I'm not sure what day of flower that was, but I can probably figure it out from my pics. I'll take a look.

Yes rot and mold are my biggest worries too, leds seems to make so much denser buds than hps.
Anyway your plants looking awesome!

Oscillating fans help immensely with bud rot

very nice canopy managment and plants.
regarding soil mixes/cocos i just encounter the oposite regarding deficiencies, having usually more work to get it dialed in in cocos then in the soil mix.

Oh I totally agree, once you dial in a good soil mix the plants grow so nice and easy. My problem was, I got covid last summer right when I needed to transplant, so I didn't have the ability to drag all of the soil I had mixed inside my house to fill up my 4x4 bed, so instead I just filled up my 3.5 gallon air pots with it. I knew I would have to start feeding at some point, that's just not enough soil. The plants looked amazing all through veg and they would have killed it in that mix in a bed or even in 15 gal pots. Coco is a challenge to dial in, I still have trouble with it at the seedling stage and in trying to keep bonsai moms alive in it.

Totally agree. I've got a ton of air movement above and below the canopy, and I keep my RH at 50% during flower. The problem was just the sheer size and thickness of the colas. There wasn't a trace of rot on the outside, it grew deep inside of them. I've had that problem in the past in skunk and critical mass plants with big colas, some plants are just prone to it. That's why I'm growing it with 20+ bud sites instead of 8 like last time, just hoping I can shrink those beasts down and avoid the rot.

i think in the end its all a bit trial and error, especially with organics.
am prob just lucky, found a premixed soil which isnt too hot and found some good worm castings it seems (sold in a pack with charged biochar, both together are a complete meal).
maybe my dry salt isnt optimal for cocos, as its pretty rich in K by default, more trial needed, even i had all the ppms calced in hydrobuddy, could be perfected for sure.
my tents are pretty small, but i have no problems so far with 4 x 3 gallon pots in the squaremeter tent and the smaller 86x86cm tent is looking also very good with 2 x 5 gallons of soil, i knock on wood as they have quite a few weeks to go.
i do have my first soil cooking in the kitchen waiting to be reused, am curious if thats going to work as well or even better, its a bit flying blind without analysis.
alternative is to mix some fresh soil every run, then i would know at least what i have.

Air purifiers will stop rot as well
Foliar application of ASA works for tomatoes as well, something to do with stimulating the plants “immune response”. From my limited understanding, when the plant is attacked, it produces similar chemical responses in defense, the foliar application kick starts this response without a “pest” trigger thereby bolstering defenses.
