Hi Zed, I think whodat can see some white markings on the leaves. Often mites or bugs can come from soil, it's the way when going organic. Plus when you grow inside bugs etc get attracted to that part of your house (warm, nice light, plenty food).
I would actually hazard a guess at either a mite or possibly thrips (also come from soil). It may not be but worthwhile to check and treat before they spread.
White/yellow dots = Mites
White lines or white scores across the leaves can mean thrips.
Jig, I loved the Skunk 600 pic, very apt my friend. It's good to see some nice competition entries.
Nice to see ya Gnome, hope all is good.
Wow, I can see blue sky today.
Have a good one people,
