The silver particles are surrounded by OH radicals according to you. An OH radical has an extra electron and makes the particle slightly negative. Thus it should attract an Ag + ion, and the OH should be able to supply an electron so it can plate out on the particle. I see no natural repulsion between an Ag+ ion and a negative silver particle.
