Goodies from a 2nd time newby

yellow leaf with rust stamps maybe beacause of mixing nutrients on table water i change now to a better water with more cal mag etc i give more space from light cause upper leafs was slim i have kinda high humidity last week at night but as i see last days maybe i fix it and now at night goes up to 60 on the half tent i have done topping on the veg stage (down side with yello leafs)
