Is big inter nodal space outdoors a problem?

You will want to support that plant "tomato cage or wooden stakes and twine" so it does not topple over from its own weight or the wind, that is if you want to leave it as is and not doing anything more drastic like LST or HST. [low/high stress training] To me this is your biggest threat right now is damage from the elements as the plant is growing to long and not enough bulk in between to support its self. Large spacing between nodes is related to low light. It's craving more light and will keep stretching till it hits it. One option to help slow it down would be topping and moving into more light or useing somethings to help reflect more light into its path. With topping you could pinch off the first few nodes and make a clone out of it "if its a photoperiod plant" this will cause the plant to make two new branches at the lower node just before the cut, it will invest more of its energy to recover but it will stop it from stretchering for a bit. If this is an autoflower do not top it, support it as best you can and get it more light if possible. Good Luck!
