Need to make myself clear here. Wood chips, esp fresh, in my opinion, does rob the soil of nitrogen so should be used in AUTUMN when nitrogen is not needed. In spring nitrogen IS needed. I think you would notice it more in young plants.
I first became aware of this in my garden a few years ago and talking to a few allotmenteers (?) was advised to either apply in autumn or apply in spring with sulphate of ammonia or dried blood or other high quick release nitrogen feed. (For old fashioned advice and info these old allotment gardeners know their stuff. An hour or so in their company was a great education) It's how I do it now and it works well for me believing wood chip robs nitrogen initially in autumn then returns it later in spring and summer ...as with many fresh mulches
(most noticeable in veg patch with lettuce. Sawdust and woodchip applied in spring produced slow and pale growth. Compost or bagged chips are fine)
GD, out of interest do you mulch in autumn or spring? However if it works for you that's great.
Gardening is all about learning, experimenting and being open to ideas. I try to produce best plants I can, edible or ornamental and hope to help others do it too
