Flushing plants when some wont be ready for 3 more weeks.

Like the tittle says, should i just keep using RO water until the rest of my ladies are finished? Im scrogging them so i couldnt remove them. I have 12 plants 6 of them are ready and i already harvested them but wanna know if i should give the other 6 plants nutes or not?

I'd go back to feeding, if I were you. 3 weeks is a long time, and alot can happen, so I don't think it would be a good idea to starve them during that time.

It also depends on what nutes your using. IF its organics the flush isnt really needed as this wont really effect taist, Some people refuse to flush at all as they beilive letting the plants suck them selvs dry waists bud growing time when its most needed. The last 3 weeks can double bud growth!!!
