Gg#4 blimburn seeds

1st week of flowering done not much to say she is not stretching like I thought she would maybe overfeeding decided not to flush as I just flushed her to get her ready for flowering and I'm afraid she will be over watered. I'm still wondering if I should flush her again anyone with input would be much appreciated. Going to look into some sort of co2 for the tent hopefully will have something for next week.
