OK its not too bad. I think there could be a few things happening but fortunately for you it's early and you should be able to fix it. First off Im noticing the leaves are slightly yellowed that could be from...
A) Overwatering and the plant is struggling with oxygen uptake through the soggy roots
or it could be...
B) Possible Nitrate deficiency. A lack of nitrate food in the vegetative state will often result in the leaves turning lighter in color
Also I'm seeing a little bit of the rust spots showing up on the yellowed leaves. That is likely a nutrient deficiency probably Magnesium or Calcium. If I were in your position I would do the following things to help correct this...
1) Start watering less. Both in frequency and in amount of water. Let the pot dry out a day or two in between waterings make sure the top layer of soil is bone dry to the touch before adding water again.
2) Start feeding your plant. I would use a vegetative nitrate fertilizer start with a light dose and ease into it. Also along with the fertilizer you should also start adding a Cal/Mag supplement. If you these things your plant should be happier. Good luck!
