I doubt that the crop you're growing is "all" for science, I'm guessing that it's going to be used and enjoyed too.
There's nothing wrong with documentation, it helps in many obvious ways but let's not pretend it's just being grown for the data.

week 3 1/2 sum stretching on the mmj that are nto fully into buding but everything else is doing great, i water tray every 4 or 5 days ! advanced nutrietns,and Rare Gentetics!!! wait for em, they got alot about to open up for the west coast, rare strains that people will love! Video was gonna be posted but website wont load it!!!
Update week 5 still trying to post pics on here I don't have an actual computer , tried my friends laptop , seems to be bud growing, but alot of the plants are stretching , not sure what this is due to maybe lack of light ? Hmmm
So I'm still using advance nutrients, the plants that are budding ,.are budding well but no 1000 watt kolas, , but there is very definitive crystallization all over the outter fan leaves ,. Very big trichromes
Without pictures it's hard to help diagnose but your text looks fine.
Stretching is normal for the first few weeks of flower, beyond that it could be genetics or lighting. You're never going to see 1000w colas with a LED light that only puts out 620-ish watts.
