first feeding after mid growth flush

hi everyone,
im wondering if, after an emergency flush for salt buildup, should the next feeding be at the recommended feeding schedule strength, or should nutes be re-introduced slowly? (second week of flower)
they are awlays given nothing but ph'd water between feedings.
and after the flush the run off ppm's were the same as my tap water.

I would start lower as you had to flush for excess salt already, why do it again?

thx for ur advice
answer to ur question
they veged forever, wont runinto salt build up before final flush, ive been told a mid growth flush is a good idea.
