Leaves are turning and twisting in flower!

[toneloc420]

Half of out plants in one of our flower rooms are starting to have leaves twisting and turning also changing to a dark red brown color. I raised the lights, I'm about to add a fan. Possibly pH issue or a light intensity issue. We are only coming into our third week of flower. Thanks in advance!

Wow..looks like you have a lot of issues.. don't think I've ever seen one that bad... nobody can help if you don't list your specs on everything..only 3 weeks of flower.. you're almost half way through..I personally don't think you can fix them enough to get anything good out of it...but list your stuff and we all will try and help

Without specs, they look really thirsty.

Toss that plant out stop wasting money on it, put your light further away, turn down your heat or maybe even to much wind.
