Yea I’d agree @Docnraq . I’m always amazed at how much water volume increases as they grow. It’s a bit confusing when you first start growing cause you make sure you don’t over water for the first few weeks but that mind set can be trouble later, when they go full speed ahead. When you consider the flushing option it’s like they can’t be overwatered as they get into flowering. That’s what I’ve found @Mr420.
By the sounds of things you need to water a bit more and it sounds like ur humidity is too low to low of humidity will cause ur leaves to get crunchy and dry
Also it looks like they need some calcium aswell with a touch of epsom salts
