welcome to RIU buddy!
what strain you got going? I've got two ladies that are also in their 5th week of flowering. I've got two of Nirvana's 'Ice' plants going currently..
first time growing the strain and I'm blown away with how hardy of a plant it is.. not only that.. but they're beautiful strain.
But yeah, let us know what strain and if you have any pics.. post them up bro!
welcome to riu and good luck on your grow!
peace.
