The leaves on my tomato plant are turning pale. What am I doing wrong?

Blue Roses?
It is needing fertilizer. Get a cheap one and put a few crystals around the soil. Don't get on plant leaves. The leaves will not hurt the plant. If it requirements fertilizer it will effect the production of the tomato.
Question around roses?
it sounds like they are not getting all the nutrients they call for. Make sure you mix the food properly
Which grass should I grow, Bermuda or Fescue?
If your fertilizing than you've overdone it. If its simply the bottom few its kinda natural.
If its none of the above you have a soil and mineral issue.Not much you can do this season.
I estimate its just the bottom ones and is natural.
If you enjoy not fertilized than do so with a high concentration of iron and magnesium, but keep hold of the first # ( nitrogen ) low as that may be also causing it.
Its not water related . Probably undersupplied iron and magnesium
