Mystery colombian cannabis - 13 weeks - pics inside

[Viu Caravanos]

Hello everybody!
This is my second grow. I got this plant at 3 weeks veg from a friend who told me it was from a seed a buddy of his got in santa marta colombia. she's now in the middle of week 13 from 12/12 under 600 HPS.
I discovered yesterday I was not using the right nutes!

I was using the red one all the way until now, and when I started using the blue one I stopped using the green one.
I'm using also overdrive and rhino skin (was using big bud before overdrive).
The buds are sticky and some of the buds are pretty big, but they're fluffy - not dense enough.

can it be because of the nutes? or maybe it's just because I've still some time to go? (would appreciate your opinion on when you guys think that is).
do you think I should flush it? I flushed it before 2 waterings but both of them were with the wrong nutes.

Thank you! these are all pics from about a week ago

I uploaded the pics to photobucket and copied the URL. any idea why it's not working?

I saw some posts of folks here that are really into the colombian stuff, so I hope you guys can help me

Thank you for replying!
It's not very specific about exactly how much of each elements it contains but it does say on the back:

Composition:
Trace elemnts: iron, manganese, zinc, copper, boron, molybendum, iodine, and cobalt in complex-bound form, plus vitamins B1, B2, folic acid, plant sugar, amino acids such as glycine, histidine, tyrosine and enzymes.

do you think I should flush it again (watered it two times wrong since last flush), or just continue watering it correctly?
how many more weeks do you think I've got to go based on the pics?
I've been reading that buds put on the most weight during the last 2 weeks, so if it's a 16 week strain it should just about start to do that
