Flowering issues?

Hi,
Can someone provide some advice on my White Widow Auto? It’s been in budding for several days, but it looks different to my previous grows. It’s in coco, using advanced nutrients, grow, micro and bloom. As advised by advanced nutrients you use all three notes throughout the grow, at a rate of four of each per litre water. Could at be that this is a different strain to my previous grow, as the buds on that were short stubby and fat, where these seem they might grow long and thin. Please any advice welcome. The first two photos were my first grow and the other three are the one I’m questioning.

Issue = over thinking. They seem ok.. just not done.

Growing autos you can get all sorts of variations in plants
Snowflakes all

Grow Photoperiod plants if you want consistent results, autoflowers are not going to grow the same, every seed will be different just like Photoperiod. Look into Cloning, you can clone a plant you like and then grow it for years and years.

There is also signs of slight nutrient burn, if you had excessive Nitrogen it can sometimes cause the buds to stunt growth.
