Looking mighty fine, RP!
Yeah that's weird that they stretched after 4 weeks...I don't know what to tell you, but you might be a little paranoid. They look great to me so I think they are fine.This is 4 weeks flowering 3 white widows.
Trichromes are present however not very visible in the pics.
I am kinda worried about them. It's strange, they streched some today.
I thought that part was over. The troublesome part is they only drank 1/2 gallon of water today,
they have been drinking 1 gallon a day for a few weeks now.
look at those trichomes allready
