My plant has a problem that i need help with.

She is in veg and is fed with bio grow 0.5 ml per litre and is watered every 3 days or when soil is dry...Temp is a steady 80 and humidity 60%.Tried epsom salts but has'nt seemed to work...As you can see on one of the pics the leaf has brown patches and part of the leaf has dissapeared without trace!
