Defacto, some of the cultivars I hold show deficiencies when they're growing fast, after transplant. Usually these problems resolve after the plants root in. You could give them a little shot of epsom salts if you want to do something. I would top dress them with a small amount (those are smallish pots, so maybe a teaspoon per plant, no more). But a wait-and-see approach is probably okay, too. It's early days yet my friend :)
