A few noob questions.....

I have 8 plants, all the same age, all fed from same source, same neuts, same doses, same light 20/4, same everything. A few are a much darker green and a few the leaves are starting to yellow. They've been flowering for about 2 weeks. They are 50 days old from seed, 12 week strain. Am I lacking in a certain neut? Too much of a certain neut? I've heard leaves start to yellow once it starts to flower? Sorry for my lack of knowledge here..... first grow, still learning....

Are they all the same strain?

yes bruce banner autos

even if they are the same strain every seed is a different plant. unless you are growing the same cut you’ll need to adjust the feed for each plant.

ps: they all seem to suffer from nute burn and toxicity

Overfed.

the different shades of green is from 'pheno expression' in the Bruce Banner hybridization.
Dark Horse Genetics bred this strain from OG Kush and Strawberry Diesel, and its heritage can be found in its diesel aroma with sweet undertones. Plants flower at 8 to 10 weeks. This strain does have three main phenotypes, one of which is Bruce Banner #3.
I don't know who you got your seeds from, but a breeder would have to breed the line further to reduce the variance.
