looks like it might be a touch of mag def. try adding some epsom salt to the res.

otherwise it looks pretty good man. dont sweat those old leafs, once a leaf is damaged it NEVER recovers, thats just how it goes.

definatly doesnt look "bad"

what are "high temps"

ive seen MJ grow in 90+ degrees. so unless its over that, or the plants are resting on a bulb, your probably not experiencing heat stress.
