When you start seeing those terminal leaves growing, I water my plants. I will still have them in mostly shade, getting several hours of early morning or very late afternoon sun. I will wait until the soil looks dry then water again. I slowly, perhaps every week, allow my newly rooted plants to get another hour or two of sunlight. Finally, after several weeks, there will be full-size leaves and the sun exposure will be close to full day. I then will water every few days, fertilize every week with 1/2 strength, 20-20-20 fertilizer, and the plants will be in full sun. This may not be what is the right way to go about it, but it seems to work for me.
