@ flashmp3, I answered your question in my last post with your quotation, but I copied and will paste it here.

Hi
@gr865
I ve been looking at your hole journal and I m impressed! Your plants received very good training. The buds are fattening so well! I was feeling very relaxed in my grow but seeing yours makes me feel concerned bout the fact maybe something is going wrong in my grow. I don't know why cause I've been very cautious except a foliar feeding stuff.
As you can see the buds look like children compared to yours at the same stage. I know 12 hours and 45 minutes of lights and 11 hours and 15 minutes darkness may add extra time to flowering, but I don't think there is a huge visible difference on the buds. Blue dream is well known to produce nice big buds.
What do you think about it? Coco is a form of Hydro, so it should get faster growth than soil, my buddy that I am assisting in his grows is growing in soil, with the same genetics as I am growing and he might do one to two zips off two plants, I just turned 17 + zips off 4 plant and it was not that successful of a grow.
Looks like you have a Mag issue, and probably Cal and Mag. I would definitely increase the Mag, I do this by adding 1 gram or 0.25 tsp of Epsom per gallon of water and 1 + ml Cal/Magic. That deficiency will cause slower growth. I know very little about growing in soil indoors.
What is your feed schedule?
I m growing in biocanna soil with more than 20L pots, 4x600w bright full spectrum leds + 1x300w (to give the canopy around 70000 lux), temps at the base of the plant 20 degrees and 27 at top canopy (Celsius) , colder at night is 18 degrees,...... Don't see why it s not getting bigger
It s like your plants were flowering twice faster!
(I know it promotes bigger roots bigger branches so bigger buds)
Is your trunk planted in a rockwool?
No, I start my clones directly in coco. And I have never heard of RW promoting roots and branching. One of the factors that promote trunk size is having a fan blowing on the seedlings or clones 24/7. Depending on the strain I may use Silica to promote stem strength.
Good job man! You did wonderful job
