Hmm, these kinds of these are a bit tough to diagnose without more info. What kind of soil are you using? Organic or synthetic nutes? If organic, which amendments and if synthetic, what line up? Whats the pH?
The weather wouldn't really cause that look on your girls, this is either a deficiency or perhaps even bugs.. more than likely a deficiency though but without knowing your pH there is no way to be certain.
The problems seem to only be on your newer growth which usually means that it's not a macro-nutrient deficiency but a micro-nutrient one. Usually you get micro-nute deficiencies appearing if your pH is out of whack, it's not that you actually have a deficiency but your plants just can't access it due to pH lock.
