Go full strength. I grow in coco and other than when they are seedlings just starting I typically use full strength nutes. That other guy mentioned salt build up, that's generally only a problem in soilless mediums if you aren't watering until you get runoff. I typically go for 30% run runoff of the volume I'm watering with. The runoff makes sure that the old nutes are flushed out and replaced with new nutes. Like he said it is not as important with organic due to organics not coming in salt form, but if any of your nutes are inorganic just be sure to flush. I would also use real growers recharge or great white myco if you have any to help it recover from the transplant shock faster.
