I am growing in DWC and the water has developed these white flaking stuff. From researching it looks like it could be root problems?
The plant itself seems okay, maybe I should flush with plain water (chlorine in tap water should help with bacteria?)
How bad is this? Water looks kind of clammy.
Should I add hydrogen peroxide????? I have 2 plants going the other one seems fine?????
problem is the critical kush while the jack herer seems to be okay.

I think I will post in MP as well, more hydro growers there.

need pics

Okay (not the best pics hope they help) plant on right is Jack Herer, seems to be doing well,
On the left is Critical Kush, was slow in seeding and slow to start growing. I emptied the res yesterday so the water may not show all the
flaking but it seems to be still there.
Roots look okay, cannot see any obvious problem.PH is 5.6 neuts at 1008PPM room temp 65* - 82* Light 400w MH
Will try and get better pics outside latter today.

Thanks SG

I will try to repost pics here

Nuts can mix then solidify..especially if they are cheap made and even if they are good the chelation some times causes this...lower ppm IMO if this continues ...just my two cents

I have done 2 flushes and it seems to be clear now.
I washed out the buckets with hydrogen peroxide so just wait and see, everything else seems fine.
Thanks for thar info, Will keep tabs on the PPM as well.
