That may be a contributing factor, but more than likely you were driving them pretty hard with the VPD up and and lights blazing. That could have forced nute uptake with the needed water.
I'd do a review of what you've amended with for the past 10-14 days to tally up what could have done this.
I'd do a simple compost tea with a little ground kelp. Make a SST and add it along with the tea and apply. If you have some recharge or some other inoculate I would administer at the same time. With Recharge, I brew it with the compost tea for the last 3 or 4 hours
