yes but not muchthey look ok to me, have u given them any magnesium yet
I agree, looks like it could be getting overwatered, also the dark green could possibly be too much nitrogen, but I would let them dry out completely, then cut back a bit on the amount of water you are giving them and see how they respond.If you have been good with the fertilizer, and haven't given more than 1/4 the recommendation, then I would have to say you are overwatering. Let the soil dry up till the pot is light. My 2 cents.
i think i know what's wrong, the first two pics are in the side view,
