It depends - on what tuning guide you use, based on the cut of the main. Tuning guides are available on the menu under "Info", "Articles of Interest", "J/30 Rig Tuning". 1800 pounds is not abnormal. The tighter the uppers are give more mast pre-bend due to the swept back spreaders.

Make sure you have the rig centered before starting any tuning. I use the bucket of water on the halyard trick. Just hang it over the port and stbd side at the same position fore and aft. Mark the halyard so it is even with a reference point like the top of the toe rail and adjust the rig so the halyard mark is at the same position on both sides
