The capacitor charge is defined to Q which formally is always positive. The capacitor charge can be negative in cases where one plate is defined as the positive plate for some derivational or practical reason and this plate happens to acquire a negative charge (e.g., see § 5.5). In electrostatic equilibrium, the plates are EQUIPOTENTIALS.
When an empty (discharged) capacitor is connected to a battery, it slowly charges up as one plate fills up with electrons, while the other plate has electrons drawn away from it towards the positive terminal of the battery, resulting in one plate having a positive charge and the other having a negative charge.
Capacitors are UNSIMPLE dipoles. The capacitor charge is defined to Q which formally is always positive. The capacitor charge can be negative in cases where one plate is defined as the positive plate for some derivational or practical reason and this plate happens to acquire a negative charge (e.g., see § 5.5).
The capacitor potential is always positive except in cases where the defined positive plate happens to have a negative charge and therefore a negative potential (e.g., see § 5.5). In words, capacitance is how much charge a capacitor can hold per capacitor voltage (i.e., how many coulombs per volt).
The amount of charge exiting from the negative plate is exactly equal to the amount of charge that enters the positive plate, so the entire capacitor structure remains charge neutral. As voltage increases across the capacitor the voltage across the resistor decreases, which means that the current must also decrease.
You are correct that the electric field on the capacitor causes charge to flow from the negative plate to ground. The amount of charge exiting from the negative plate is exactly equal to the amount of charge that enters the positive plate, so the entire capacitor structure remains charge neutral.
