What is this?

Fairly new to growing. Saw this milky white substance on a few of the leaves. Both kush's. one bubble gum the other purple. Look at the pic, dead smack in center if you can zoom.

tried research and books to find out whit it is. Had a slimy texture, white, wasn't hard but can't figure it out....

Anyone know? If so, causes and cures?

Thanks for any reply!

are you foilar feeding with anything with beneficial bacteria? looks like water pooled in your leaves and some slimy bacteria grew there. wash it off.

Thanks. No feed as of yet. Just the Fox Farm Organic Soil that has some nutrients already. Just did the transplant into a bigger pot and starting nutrients early next week. I've been wiping it off. Hopefully it won't become an issue. again thanks, keep you posted.
