Slow flower

Hi guys,

one of my Moby Dicks from Barneys looks like this




The stretch was just too much and she stretched to the point where I can’t hang the light any higher. So there is lightstress for sure. She’s growing in a hydro environment EC 2,5, pH 5,9-6,2

I grow the same strain in the same tent with the same stats and the plant looks like this

There is also a girls scout cookies which looks like this

They are on day 32 of flower…

What is going on with the middle plant? Did I do something wrong or is it even the same strain?

Would love to hear your thoughts
