Those leaves are from revegging. Weird, huh. If your plan is to grow her larger keep her under light 13+ hours a day. If your goal is to leave her outside with less than 12 hrs of light she'll flower.
For future reference, when growing in coco keep the coco wet by watering (actually fertigating as each and ever watering should contain nutrients) 3+ times a day with 10-20% runoff. Yeah, you can get away with 1 or 2 a day but the plant won't grow as quickly or reach its full potential. And always use hydro nutrients. For young plants, 1-3 weeks old (applies to young clones as well) use half strength. Up it to 3/4 strength for a week or two and then use full strength. Once the plant is flowering, about 4 weeks into flower cut back on calcium by a half.
Growing in coco is one of the best growing methods as long as you can fertigate the plant(s) 3-5 x's a day and you can deal with the waste water. You can grow 6-8' trees in 1-2 gallon pots
