Hi i wont start flushing before week 10 , And as you only grow 10 weeks it will be enough to do 2-3 good flushes at all, that would be done in one week ( i dont think that you have a big nurtient buildup in the soil. and you took a small number of nutrients at all. So let them grow until week 10 if tichomes are mily/amber start to flush
you can give her now some blooming frtiliser/pk booster, and some molasses for the microorganisms in your soil.
Try to lower the temps/ give some airflow to pervent mold
