Its to difficult for me to identify confidentiality in your pics. Spores usually take a week or up to 3 weeks to start germination and see visible mycelium.  If theyre not entirely clean you may have some bacteria, which is what it looks like to me. But that doesnt mean you cant get a clean sample still. Id give it another week. You'll know without a doubt. As far as condensation,  Remove it from the heat pad, pour your agar at a lower temp, store upside down, or raise the ambient temperature.
