I know it sounds like a pointless question but I feed my girls from the drip trays from Week 2,when it comes to the flush do I need to flush the soil through or do I just water from the trays as usual with clean water
I do not water the soil I fill my spill tray and let the roots draw from the tray.
What I would like to know is if I will get salt build up and whether I should flush the soil at 5 weeks and at finish or just wait and see if I have any problems
Your the first person I've heard of that waters that way.The roots should not be coming out the bottom of the pot in a soil grow but if it worked for you than so be it.I would still flush the last week or so to remove excess salt and nute residue.

I am a newbie really i have had two grows before these two the first was stunted cal-mag deficiency got about 20g the next two were in coco and I fed from the bottom ie drip tray and got 60g and 90g respectively
The roots don't come out the bottom I have a layer of clay balls at the bottom of a square 11l pot covered in either coco or soil I have the matching square spill tray I fill to the brim then leave an hour before topping up
You are basically using a wicking method to feed and water your plants.
The medium can still have quite a bit of salt build up.
I would recommend watering (straight h20) from the top at this point to assist in purging any remaining salts from the medium.
You will want approx 10-30% run off each time until chop.
You could continue the way you are, but should give it straight water for at least 14 days before chop.
