what's wrong here? over-watered? nute burn?

As they go into flower they use up a fair bit of H2O. The top 3 pics, centre pic is showing the leaves curling and the serations starting to point up. This indicates thirsty OR to much water, I would agree with the others and give them a good drink, considering the heat.

 

The Kali's just look real thirsty to me. Nice plants though.

An medium largish plant will drink 6-7 litres of water per day i would have thought

And really in the ground long slow deep waterings are the go imo

Long slow & deep is good. Im watering in the morning daily 16 litres total between 4 plants for the last month temps have varied from high 20's to high 30's. After a hot day like today a little more tonight with the sprinklers.
