Urgent help needed!!!!!

FUCK FUCK FUCK FUCK FUCK FUCK FUCK FUCK FUCK. Im growing in a drip irrigation system the plant is about a month into a flower I've just been to water some soil plants I've got growing next to my main one and realised that the oxygen tube wasnt connected to the air stone so the roots have been without oxygen for almsot 3 days. All the bottom leaves are droopy pale green and some are starting to wilt, the hairs on the bud have turned a dark brown prematurely. I dont know if I've fucked it up, is the plant going to be alright and is there anything I can do to save it and get it back to its normal healthy self??? ALL ADVICE IS WELCOMED AND VERY MUCH NEEDED!!!!!!! THIS IS URGENT!!

If it is very sick you might have to go back to 18 hours of light for a few weeks to let it re grow vegetive. Keep the pump working properly and do away with the air stone completely. Use oxy plus to kill any pythriums.
