[xrayx]

hi ppl

ive been growin using nft for a few months now and ive got five plants on a nft table that are 3 weeks into flower and are looking great, the problem is where the nutrient solution is pumped onto my table the roots around it are turning brown does this mean ive got root rot or is this meant to happen. if i have got root rot is there any thing i can do to stop it or will my plants be ok untill harvest time.

any advice would be helpfull as i dont wont my plants to die.

I have NFT you need to get some liquid oxygen in your tank. I put 3 small spoons full in my 9 gallon tank. Do this a couple of times a week

ive been putting liqiud oxygen in there for a while i put 15ml of liqiud oxygen in my 30 litre tank but i was told to much liqiud oxygen will kill all the microlife ive been giving my plants (canna zym). il be happy to just leave it alone if i new it wouldnt kill my crop before its ready, but ive not got this problem with the trays in my veg room......

The oxygen breaks down over 24 hours, simply putting the oxygen in and the next day upping the EC level up a bit will do it
