Take it easy poker. You have no problems yet. Don't worry about the nuteburn. It's normal, even a good sign. Maybe you can be more careful with watering. Not water itself or PH. You don't need to worry about PH, your soil will buffer it. And don't even think about giving nutes if you have nuteburn!!!
Water until you see the water from drainage. Not like you're doing now. This will make you to keep the dry circle little longer. Like one day or more maybe. Give water when the pot is no more heavy by weight or when the leaves are dropping back, or when the soil is dry (Use your own easy method). I'm also checking drainage holes soil, effective way to tell if the soil is dry or not.
