We're Dying

Should I flush my plants? This started as yellowing, and after I fed them they only got worse! I really don't know what will bring it back. And now my other plant which hasn't been fed yet is turning brown at the tips.

Before:

After:


New plant turning:

think ya fed em to much give flushin a try, what soil you usein

bottom leaves turning yellow and dying off is a sign of overwatering..
if on the still green leaves the tips are brown it's nute burn

I am using Expert Gardner perfect mix soil. I uploaded some more pix of the leaves.
The Plant I Fed:


The one I didn't:

the second pic there looks like a worm.

I put hydrogen peroxide mixed w/ 2 parts water on the leaves, should I do it again?

Try this website Web Gallery Wizard™ look in the insect section, looks like these things called leaf miners..

That looks like the lines I have. Anyone know how to treat "leaf miners"?

I have me a nice shot of some nice fingerprints to use in my next crime.

These are what the tips of the upper green leaves look like today. And some more fingerprints for your next crime...

After looking at the last pics does anyone know what I should do? I don't want to water if I'm overwatering and I don't want to flush if I'm overwatering either...

Went ahead and watered both, and fed the one I hadn't before. All I can do is hope for the best...
