Probably lock out from your pH being too high. For soil less growing shoot for about 5.6 in veg and 5.8 in flower. For soil less, follow the hydro recommendations.

I believe that's nute burn. Next time just flush with ph'd water and see if that helps. Also lower the dosage of the nutes.
Never go above the required dosage

I just saw the tips of the leaves on the other plants and I do believe that it is nute burn, I think these guys are spot on...

Just a recommendation, I think that the recommended height for a 1000 watt is 24" maybe try raising your light as well...
But, I don't know how your exhaust is setup so maybe I'm way off...

so...should i flush it, or just water it with low ph'd water with a half gallon, or just wait till next feeding???

You want to avoid over watering so when it needs another watering. Water it then without the feed and see if that helps
