Flushing, flushes out available salts, damages microbial activity, and can temporarily drowns roots. This is why your plants stop growing for a few days after you flush them.
In general, you dont really want to flush unless you have a build up of fertilizer and your plants are burning.
If you use a fertilizer that says 2-3-4 for example, you dont need to really flush, just feed plain water for a week or two before harvest and your fine.
If you use a fertilizer that has high numbers like 12-22-30, you need to flush before havest since the fertilizer is so strong.
From my experiance, you actually get better results by flushing really well like 10 days before harvest, then just let your plants dry out and try to harvest when your soil is dry and your plants are just about to start wilting. (but this is my opinion)
DONT use nitrozym!
DONT add any fertilizer
You can add some superthrive if you want, but its best to just leave your plants alone. Continue feeding them 1/2 strength of what you should be feeding them and slowly bring the PPM back to 1100.
Your plants have a good 3-4 weeks left if the light leak didnt mess them up. (Just so you know, light leak will significantly delay flowering and reduce harvest weight, so for future grows, make sure you dont have ANY light leaks)

I have beneficial bacteria, would flushing as I did kill off the good bacteria colonies?
but your are about mid way
