Should I add nutes to these? I will karma for help :)

Since I took these pictures yesterday replaced the water on my 3 week old plants 2 from seed. I had two gallons of water then 2 tsp of grow big , and 2 of big bloom, and my water is only at 575 ppm. I have slight curling on the edges of some of the leaves, and one leaf on a plant had yellow spotting. That is why I did the flush. Now after the water replacement ( distilled water + nutes ) I am only at 575 PPM do I need to change?

Could you post pictures? It sounds like you're over-fertilizing if anything. How long since they germinated?

here are the pictures

They're looking good, I'd just keep checking the PPM every day. If it's at 500ppm in the morning and at the end of the day it's up to 600 you know they're mostly just drinking water and that's all you need to add. If you start at 500ppm in the morning at it's down to 400ppm at night you know they're using lots of nutrients and you may need to add a little more.

As it stands I'd just keep it at 575 and take regular readings. If the plant gets worse then I'd worry about it.

so far its staying at 575 to 590
