My recommendation is to not look at them, but look at the overall plant. Wait for the calyxes to swell, the hairs will recede into them.
Look into it, there’s better descriptions than I can give. You start to get a feel for it, and can tell from a mile away when they’re ready. Also, post a better picture. Can’t really tell much when I zoom in, but they appea to have plants of white hairs.
