The way I understand apical dominance is the shoot nearest the light gets most the food, light and grows the largest
In the first picture you have one main shoot getting all the light and pulled the rest of the shoots down so there not getting any light.
If you lst the plant, all the canopy is...
Update
The seedling are looking good but one has twisted leaves, gro-sure seedling and cutting soil is high in peat moss and so the ph could be low, I have top dressed with a very small amount of garden lime.
one of the pots in the picture looked very small compaired to the plant.
When I turn the plants over to flower the top new growth tends to go a pale green and you get a cluser of thin leaves, simlar to your about 7 days in flower 12/12.
your plants look very heathy, but there in early flower and still have a lot of stretching so your pots look too small for the plants, I can see you having alot of problems soon
I would pot the plant up asap, not ideal but needs to be done imo.
This is the way i look at it
6" fans rvk 3 = 0.180kwh (60w each)
4 x desk top fans = 0.080kwh (20w each)
2 x 600w hps = 1.300kwh (650w each)
0.15p per kwh
6" fans ( 0.180 x 24(h) x 7(d) x 12(w) × 0.15= £54.43p (6" fans)
desk fans ( 0.80 x 24(h) x 7(d) x 12(w) × 0.15= £24.19p(desk fans)...
Aren't We All lol
Often remove some of the lower bud sites when I am get low, cut them up and leave then on the hood over night, its not the best smoke but does the trick.
It will be close but your buds are well developed and there 4.5 weeks till new year
3.5 weeks in flower and 1 week to dry the buds (I think its possible)
