Indoor Why no density to my buds?

[firsttimegrower12]

Strain: Fantasmo Express
Medium: Royal Gold Tupur Coco
Light: 2-288 Rspec(20/4)
Driver: HLG-320-2800A
Nutrients: Sensi Grow A&B, Sensi Bloom A&B, Alliance Biologics Inoculant, Earth Juice Microblast, Hi-Brix Molasses, Fish Shit
Temps: 75-81

Plants grew pretty well the whole grow....no signs of any serious problems. Small amount of light stress on some of the leaves on the buds near the top of the canopy. I was toeing the line on my lux levels at the canopy the whole grow...so I am pretty sure that lack of light is not the Cause. What would cause it not to be dense? Could the pH of the root zone have gotten off or something?

I grew Fantasmo recently, and my buds looked like yours.
Didn't matter, because it's potent.

I've run her before, great smoke but buds weren't super dense! Great daytime meds still!!

Isn't bud density (mass or weight per volume) just how much the bud sepals/leafets have stuck together during bloom? Buds being hard/dense or flulffy doesn't mean they are any better (in my opinion). Theoretically. I'd presume that fluffy buds are more potent, with more light- and air-exposed surface area, particularly compared to rock-hard buds. As a grower, I'd prefer larger, more open buds vs. golf balls.

What you have looks like what I usually get -- good-sized buds, but not high-density. If I want dense buds, I squeeze/compress harvested buds with my fingers.

pH can cause issues, a low pH will lock out P, low Phosphorus will affect density. No way to tell here, with the fan leaves gone.
Could also just be the genetics, more sativa leaning, less density.
As to preference, personally I have none as long as the smoke is fire.
But... if I'm growing for market, dense hard nugs are what sells.

Part of it may be also your growing under QB, an even canopy is the key.

I find density to come to all strains nearing the end, most my chops are around d90 to 100. Nugs so hard you can bounce them.

:smoking: mate, I'd say part of it is that FEx is a known sativa-type bud builder, more open in structure and not particularly dense... Normal, for the ghost Train Haze heritage in her... Also, I see more leaf than is normal, which is hard to point out exactly why, but the look is of too much N going in during bloom,.. I know Sensi isn't very P heavy, and their Ca-Mg product is very N heavy... Did you use the coco specific nute line?
Hmmm,... I see some possible micronute defc. too, looks similar the light stress symptoms but it's on the lower tops as well,... see the interveinal color fade on the single sugar leaves, and the odd contorting? Might be some mild Zn defc.,... I can't say for sure that leads to more airy than usual buds, but Zn plays several key roles in the plant, and any lack along that chain can lead to poorer performance including density.... Another distinct possibility is that this is just an odd pheno, simply won't make the status quo buds....
Review your total nutrient line for N content and how it's ratio matches up with P and K....

I included pics of the back all of my nutrients. I DO NOT have the Coco specific line. I didn't know it existed until I had already bought these at a local hydro store a while back. Lol.

Also, I included some pictures of my FE right before I chopped her down. Def gonna make my next plant's buds/colas look small! Lol.

those look much better!
.... Coco is a weird medium man, peculiar cation exchange capacity properties (CEC),.. coco hogs Ca and Mg to a lesser degree, binding it to the particles and keeping it from the roots uptaking it until a certain saturation level is reached, then the give-take gig starts working... coco line has elevated Ca and Mg levels to compensate for this,...the regular Ca-Mg is pretty N heavy, can be a "hidden "source of N,.....
EJM is bomb-diggity stuff, my [HASHTAG]#1[/HASHTAG] fav' product for micro's supplementation! Most are very reactive metals, so they need strong chelation to keep them available,.. this can be lost over time while in-pot, so I supp' them weekly just to be sure,....
