Hello. From what you are describing, it looks a magnesium deficiency. A little epsom salt will fix her up. Dont over do it tho. Add about a half a tea-spoon to a gallon of water. Watering, Poke your finger about 3 inches in the dirt, if it's dry, water it. If its moist. let it be. You can use the "lift the pot" method to check your plants. A light pot means you need water. Heavy pot means it's cool. hope this helped, peace.
