This is more likely coincidentally occuring and not caused by your slightly late irrigation.

Red stems and that dead leaf reminds lack of phosphorus, early flower requires bigger PK part in feeding. Sometimes if soil overdries it makes either bacterial fauna death or salt build up, that leads to some ph fluctation or nute imbalance ...

When you wake up in the morning your plants will have recovered. They might be a little crisp on the edges of leaves afterwards but it will recover. Just remember durring flower you need to water way way more often than
