Can you increase the day temperature to at least 80 F and the RH to somewhere around at least 60%?

Some people get humidifiers for the humidity issue, they're inexpensive ($25).

I'm not sure how you'd address your temperature issue.

Bacterial issue:

Sterilize the cutting tool and remove the infection. Burn the removed portion.

H2O2 can work too as was suggested. Gotta make sure the infections stop before you can stop applying.
