56 days is typical...8 weeks....

is that flushing something I would really really need to do late in the veg growth/early in flowering? I recently realized I had too much ferts in my babies and flushed them out...they started back growing well and stopped drooping...but would I need to do this again? (I'm not giving ferts for a while since the soil already had delayed release nutrients)...And is there a significance in doing that at that stage or did you just need to do it?
