Your ladies just hit flower, it's recommended to continue veg nutes for 1-2 weeks after first signs of flowering.. this will get the most of out the plant, although it will add on time to the grow.
I personally would do a water only at the correct PH and get them back happy.
Some people even do a flush between veg and bloom so this is a option if you don't wish to continue veg nutes as I recommended.
But personally.. i would do a water only, get them back happy and lower the ppms so no toxicity. Then continue veg at a slightly lower dose so they won't burn anymore. After a week or two when the vertical growth has totally stopped, then switch to bloom.
This method will get you the largest plants possible and the biggest yield.
If you have no more vertical room, and if your needing a harvest asap then my method wouldn't be ideal. Switching to bloom would be your best bet, this will keep the plant smaller and a faster harvest.
Goodluck growmie 🙏
