It looks good right now, give her about another week before you start any ferts. Then start out about 1/8 dosage and see how she responds. She won't darken up for another few weeks. You don't want dark green, that is a bad sign. The color she is at now looks perfect. If she starts getting to green it is a good sign you are over feeding which will wreak havoc on your soil, cause the ph to drop quickly and then cause problems with nutrient lock out. Go slow, it is always better to under feed a little that over feed. Once you have overfed it takes a week or more to get back on track.
