Yellowing/brown tips of top leaves. Heat-burn, light-burn or both?

steveaustinstarted grow question a year ago

Top leaf tips turned yellowish, brown with curling. I'm leaning towards light burn as the cause, but noticed it started occurring during the recent hot weather. I've raised the lights, but am wondering if this could actually be related to the heat.

Looks like nutrient burn from prolonged high levels of nutrients. Some phenotypes are more sensitive than others. They usually start with the tips turning a whitish color before turning brown. I usually back off nutrients if they all start to pale on the leaf tips. I would use less nutrients in your mix.

Wit tat ml/l you shouldn't been seen nute burn unless u giving on reg basis
