Water plant help

Here it is. The whole code. sorry for not being tidy. I just need to remove conflict between manual turn on/off and the sensor reading. I need to isolate.

int waterPump = 2;
int waterPump2 = 3;

int manual;

String readString;
void setup() {
  Serial.begin(9600);
  pinMode(waterPump, OUTPUT);
  pinMode(waterPump2, OUTPUT);
  digitalWrite(waterPump, LOW);
  digitalWrite(waterPump2, LOW);
}

void loop() {

  char c;

  if (Serial.available() > 0)
  { c = Serial.read();
    readString += c;

  }

  int humidityRaw = analogRead(A0); // 1023 to 0 ===> 0 to 100%
  int humidityReal = map(humidityRaw, 1023, 0, 0, 100);

  Serial.println(humidityReal);

  if (c == 'L' || c == 'l' ) {
    manual = true;
    digitalWrite(waterPump2, HIGH);
  }

  else if (c == 'P' || c == 'p') {
    manual = true;
    digitalWrite(waterPump2, LOW);
  }
  else if (c == '1') {
    manual = false;
  }
  if (manual == false) {
    // do automatic stuff

    if (Serial.read() == '1' && humidityReal < 50)
      digitalWrite(waterPump, HIGH);
  }
  if (humidityReal == 50) {
    digitalWrite(waterPump, LOW);
  }
  if (Serial.read() == 'A' && humidityReal > 50) {
    digitalWrite(waterPump2, HIGH);
  }
  if (humidityReal == 50) {
    digitalWrite(waterPump2, LOW);
  }

}
