600 ppm for the next week would be alright as the buds still have life in them.
maybe not all 600 of those ppm's should be PK though it may well be too strong being its all P and K.
Maybe use some micro with the pk for *this* week and maybe not so strong ? I dunno .. your pots may be small and need more food that your aware hence why 600 pppm seems good to you.
In a week lower it to say 300 ppm with just a PK booster to start clearing the soil in preparation for its last weeks / 10 days.
I'm testing to figuring out what works and what doesn't it could take a few years before I nail it ..
This current flush I used a weak PK booster Mix at the rate of 1.5 ml per gallon for 75 ppm
My reasoning for the weak mix is to encourage them to strip reserves from the leaves and root / lower stalk and not just keep root feeding.
After 3 days of flush ( in DWC ) the leaves are yellowing and showing deficiencies
4th day (today) the ppm was back down to 45 ppm the waters starting point so I reapplied the 0-10-10 PK booster at the same rate to get 75 ppm above the starting point , to give them something but not everything they need.
The idea is to force them to cannibalize themselves as the end approaches but give something to work with at the same time.
In the spirit of giving them a little to work with , today after reapplying the PK booster added 15 ml of cal mag 15 ml of potassium silicate.
Its a Therapeutic dose being all in it reads 200 ppm above starting ppm when mixed with 20 gal.
In three days I will add 30 ml more of the pk booster *maybe* 15 ml Micro to help the buds with any incomplete business.
That's for the the first 10 days or so

The last week or four days I plan to do straight up water plus a extended dark period.
This should work the same for you even though your in soil-less a weak feeding is a weak feeding and will have the same effect as it does in dwc
In conclusion
Consider feeding a lower nutrient ppm more often instead of higher ppm less often.
I estimate your plants have about 3 weeks left , sorry for the long winded reply

Question... my plants are week 9ish from flip. They probably have 2 weeks left. They aren't real dense but I think it's a light issue. There is a full 50 cubic foot of green for 600W. That said, I'm thinking of going flush for 2 weeks. I'm wondering if just 400-500ppm of just p/k for a week might help. I think my AN LINE before sups is 5-5-5. After sups I should be running about 5-10-10 or so. I feel my plants are N heavy. Not toxic but wondering if that may be hurting me a bit. Either way, I'm going to start starving them of N now. It's just a matter of adding P and K.
Thoughts??
