How often do you water/feed the plant?

you should really try and get your temps lower! 65-75 is optimal for vigorous plant growth (provided all other elements are in check as well) once temps start reaching 82-85, plants growth is stunted, this is because the plant is exhausting so much energy trying to cool itself that very little energy is left for the plant to use for growth and development.

not sure if you've sen this before but if you haven't, def book mark it and go back to it anytime you see a deficiency with threw your leaves. our plants will always tell us exactly whats wrong sometimes we just have to know what to look for.

Okay so I'm going to lower my temps tonight, it shouldn't be a problem doing it but what is the dark color on the leaf from? Heat stress? I don't believe I over nute or over water if anything I'm under nuting
