to flush or not

long story short, I have 4 plants in flower - I don't know what strain they are - all four are different - 2 plants have 20-50% cloudy trichs and crystals no longer forming - 1 plant is about 3 weeks behind those and the last plant just threw her first hairs last week - all are in one bubbler system and can't be separated - should I flush? mahalo

I would definitely do at least like a 25% strength fert, but that's just a suggestion I've never done hydro.

Ruff question...

I'd say lower the nute concentration and start flushing when more then 70% of the trichs of the two plants have become cloudy/amber.

It's a bit of a strech, but I think this would give them all a nice chance at a good harvest.
