Dark green to light green

[pete2]

One of my plants turned from dark to a light/bright green color. I don't know if it is anything to worry about or not. Here are a couple or pics to show you.
Appreciate any comments

Hey pete
Im in my first grow and just had this happen with my girls and from what I have been reading it looks like a sulfur deficiency and can be fixed by adding a teaspoon of Epson salt to a gallon of water. I did add some Epson salt in my last watering. I think I seen an improvement. But as I said this is my firat grow ao cant be certain.
Good luck and happy days

Do you mean 1 tee spoon per gal of water? I'm using hydro, my system holds 44 quarts of water all together
Thanks for posting

Hi Pete, do you have any recent photos of your plants?

Thanks for the reply and yes I have recent pics. Other than the color change I am getting a lot of what looks nute burn. The biggest one seems like it is pretty fragile, and the stems are not as strong as they should be. On the bottom of the plant looks like the leaves are wilting, I think it's because there is very little light that gets to them. Would it help the plant if I cut all of them off? Because it is 30 days into bloom, not sure I should thin them out or not.
I would appreciate your comments about this.
