A smell like sulfur/ rotten egg smell

it seems one of my ladies, Kandy Kush has developed a rotten egg smell, whenever i am watering her, out of the drain of the hempy bucket shes in. my other lady is not . i use hempy buckets, 3 part flora series and ph my water around 6.0-6.5. usually stays no colder then 65 in the room and keep it no hotter then 80. humdity is about 45-50. think shes got root rot somehow, even though i am watering every other day and push enough water through that each watering its complete refill of nutes, after every 3 feedings i flush with water. except for 1ce i accidently fed 4 times. is there anyway to salavage? going to flush another gallon of water through maybe i could mix a little hydrogen peroxide in to help? been also foliage feeding to help her last a little longer, all my plants just the 4th week of flowering. thanks in advance for any replies, her leaves and foliage though look healthy.

so i was checking, and found that you can use food grade hydrogen peroxide to effectively cure root rot, but it can kill small plants. so i add some not alot, but hopefully this will fix whatever is going on, not 100% sure it is root rot, havent saw anything that can cause a rotten egg smell / sulfur. its not the water i am using, checked all of that. so the only thing i can think of is root rot, but hopefully this will fix, dotn have the money right now to make a run to hydro store for something that costs, had the fg hydrogen peroxide.

h202 will help your root rot, but if you have any other bacteria it is going to wipe out all of that too. I'm referring to the beneficial shit obviously we want the bad gone. Hopefully its the roots that are damaged, maybe try oxygenating your water. I found great results after buying a res and airstone. I grow in soil and soiless mediums, but I bought a 13gal res, a pump/hose to effectively get out water, and an airstone and I have seen the benefit in my roots and plants overall vigor/health.

after this grow, maybe i will look at a 4 plant set up thats full hydro, with pump and res. well 4 plant for right now, but if we move then just going to wait and get like 10 plant one or something. yeah it sucks about it might kill the good bacteria in there, but the way it smells not sure if there is.
