stu914 Posted September 19, 2021 Share Posted September 19, 2021 They look overfed, bubblers take far lower strength nutes than any other system, speaking of roots, put a pic up if you can. 1 Link to comment Share on other sites More sharing options...

badbillybob Posted September 19, 2021 Share Posted September 19, 2021 bin them, bleach out everything, replace air lines stones and hydroton, and start over. thats what i would do. i used to try fighting it with pythoff, h202, endrosan 8 and bleach etc, but the damage is done, and imho, its just wasting money on electric. id also consider insulating your buckets and keeping an eye on nutrient temps,. i know its not what you want to hear, but thats what i would do.. 3 Link to comment Share on other sites More sharing options...
badbillybob Posted September 19, 2021 Share Posted September 19, 2021 also, because they are autos, they cant just be vegged for a few extra weeks, so they will never reach thier full potential. ive had plants 6 or even 8 weeks in that ive binned, in the past 3 Link to comment Share on other sites More sharing options...

badbillybob Posted September 19, 2021 Share Posted September 19, 2021 yeah im sure it was, but its not clean now, is it? its now contaminated, so it will need sterilising and disinfecting before you go again. 2 Link to comment Share on other sites More sharing options...
badbillybob Posted September 19, 2021 Share Posted September 19, 2021 it will most likely have been caused by the nutrients being too warm, which gives he bacteria ideal conditions to colonise. trykeeping the nutes under 21 degrees, it will help lots 3 Link to comment Share on other sites More sharing options...

badbillybob Posted September 19, 2021 Share Posted September 19, 2021 you could try cleaning everything, hose off the roots and dose it with endrosan 8. insulate the tubs with silver bubble foil insulation. might work, but i wouldnt put money on it. me? id rather waste money on 2 weeks electric than 10 good luck 1 Link to comment Share on other sites More sharing options...
