Welcome to week 2 of flower!
They are all developing quite well. #1 is a little bit over watered I think and quite hard to LST since nodes are stacked up very close together.
#2 is starting to get some yellow tips on top. I think/hope it's just a bit of light stress, since she is the tallest and was always a bit closer to the lights than the other two.
#3 is growing very well, will get some LST today as well but due to the topping, she is a bit behind the others and just starting to produce white pistols, so for #3 , it's basically start week 1 of flower, not week 2 but it is what it is.
Because of the light stress I didn't raise up the light intensity this week. Still at 35% of the Sanlight (~24DLI).
Nothing else to say right now. I hope the yellow tips of #2 won't get worse, that #1 will push a bit harder and #3 just needs to stack up those pistols
