WHATS THE CAUSE...

hello growers this is a soil grow only about 3 weeks I have this one branch that seems to be having problems and I'm not quite sure what the cause the rest of the plant is completely fine

Hum. I see some light sots on leafs and wierd new growth. Need some more info. Whats the ph if your water that you are giving the plants and what type of water, whats the pom if your water? Are you feeding your plants and if so what are you feeding? In veg or flower. What genetics?

What's your relative humidity? Are you in a dry environment? Do you have a fan blowing on your plant?

I get wrinkled/buckled leaves and I'm in a dry environment (20-25% humidity). It seems to be more on new growth, like yours. I've assumed its my RH.
