thanks guys thats what i thought i have added more water to my tank so that should take the ppm down to where it needs to be how long will it take them to come back and will the fact that i just changed the light to 12/12 hurt any thing
It does stress the plant a little which means slightly decreased overall yield, but they should be fine as long as the problem is addressed. In about a week or so they should show signs they're recovering.
