Nitrogen deficiency/ toxicity

Hi guys aswell as battling heat issues I’ve just realised I have a lot of leaves turning yellow Iv done some digging and believe it nitrogen deficiency. However one of my other strains I have been feeding are showing slightly diffrent symptoms the ends of the leaves are turning left / right crooked and leaves are a dark green. However these also have some dying leaves drying away at the bottom. I have been feeding them all the same flora trio same mixture so would I be weird if one was a toxicity and the other a deficiency? I have attached some photos
