Is she ready to flush/begin harvesting?

[SeaWeed4202]

I was wondering if I should let her keep going while decreasing nutes, or if shes ready to start the flushing process with only distilled water.
I'm doing rdwc 5 gallon bucket ppms around 300 of gh and 5.5-6 pH. Rate her too it's my first grow

Looking fine, but you have weeks to go — at least 2 before those stigmas are all red.
