usually itmean over FERT.. but I don't think that is your problem...
the leaves will usually turn very dark green and then the tips will turn necrotic (brown)
: )
86-95 farenheit? that is hot.... But if you are out door and your plant is getting addequate airflow and water, it should notbe a problem..
is your soil soggy? muddy?
or does it get wet and then dry out in a normal manner?
