Hard to say without pics. Could be bug bites could be calcium etc..
A rise in ppm is.typically an.indicator to back off the nutes a bit. It would usually indicate the plant is consuming more water than nutrients thus "concentrating" the solution. That's not to say the extra nutes are necessarily hurting. But they would be at the moment unnecessary and potentially wasted. Get some pics and well be able to get a solid answer for ya I'm sure of it

That's only a 20-30 ppm change. Personally I wouldn't worry too much about that minor change.
Keep an eye on it for a few days and see if it keeps going up or levels off.

The light green marks sound like it my be a critter. Light green irregular lines could be a leaf miner.
