pics are in my album lads i didn't do very well with the camera but i tried under new pics 3-4 wks til the chop
1st of dragon stop hating on ya plants m8 they are looking wicked for plants from seed.
i ada look at 5 big buddha cheese last wk at 7wks and they werent nowhere near as nice as yours and he chopped 1 at 7wks n it yielded 3oz prob more like 2oz cause i no he dont dry that good, but i also no he dont give proper nutes and has a 1/4 of the space you got for 5.
you still got another 3/4wks left m8 the 3/4wks of the most bud production so they are gonna fatten up quite abit more. ill eat my laptop if you dont get at least 3oz a plant i personally think more like 4oz on the bigger 1's.
i think that the cheese genes in the cross are much more obvious than the blueberry cause they look nothing like my or other pure blueberry ive seen, yours look like a single cola plant i no you can top em to get more but some strains tend to have that 1 main cola and not that much else.
thats why i think you aint getting much bud lower down not so much the light but the strain m8, them big buddha cheese i saw looked the same just his had smaller buds and that was at 7wks!
another thing aswel dragon the leaves/plants look really healthy all still green etc i personally dont think you could do much more than you are? yeah more light is always good as is space but personally i think your doing wicked m8 id be well proud of them if id grown em from seed!
