Yep, she hungry. Find some good food for it with a nice NPK ratio. Since it's in veg, you'll want something with a nice amount of nitrogen(N), some phosphorus(P), and a nice amount of potassium(K). Something that's 4-4-4 works pretty good. Or, nitrogen heavy, like 6-2-4. You could even get 4-4-4 and add extra nitrogen. There are companies that make CalMag+, which is 2-0-0 mixture of calcium and magnesium. Mixing that and 4-4-4 together will do vegging plants some good.
