In planted tank nitrate spikes could mean the plants are consuming ammonia instead of nitrates. Then as aerobic bacteria build and start consuming ammonia the plant start consuming nitrates and the nitrates drop.
As long as the fish are doing fine I wouldn't worry.
although I would not add food for a week or so after adding new fish.
