Hmmm, plenty of time to learn about windshear, crosswinds, gusts, haze, turbulence once clutching ones own PPL. I'm not sure that training in anything other than cavok is real value for money for pre solo students! Master the basics before learning the tricky stuff. The tricky bits of experience come whether you want them or not - eventually! My opinion is that G20 straight down the rway is about max for a student!
