This is my first indoor grow and after following alot of advice on this forum it was going great.
Last week I noticed spots on the leaves. I checked the roots then and they didn’t look out of the ordinary. However today I checked again and this is what I found.
I’ve read that roots stain from the nutrients. They dont have a smell to them and don’t appear slimy. I’ve changed the reservoir to plain water that has sat overnight and cal-mag and Current Cultures UC roots as a substitute for hydroguard.
There are no light leaks. I have two airstones with a decent amount of bubbles. The tent usually sits around 22 - 24 (71-75) degrees and I have the intake fan close to the tank so its got the little extra cool on it.
What is your water temperatures?
What nutrient line are you using?
I wouldn’t be that worried as long as they’re not slimy and don’t smell. Hydroguard comes highly recommended to resolve any root issues. As long as temps are inline.
I know enough to be dangerous really. We can tag them after
Your hydro growers to tag are:
@ Myfriendis410 @ peachfuzz @ TDubWilly and @ Bogleg
Yeah you got something going on there def looks like some slime starting to form . I’m not a hydro guy so I can’t help with a treatment but @Covertgrower has you covered he’s given you the tags to the Calvary
Temp is around 19 - 21 degrees Celsius. I’m using the canna line of nutrients as well as current culture as a substitute for hydroguard since it’s difficult to get down under and professor greens cal - mag. I’ve trimmed the affect leaves just to be sure. I’ll update when I get home today. You’ve got me worried it’s the easy onset of root rot.

Always try to upload a clear picture in white light of any issues you may have to allow the community to assist you.
This is more targeted towards Hydro growers so bear with me so it’s in one place. As @Covertgrower asked; water temps are important for O absorption as well as protection from pythium. I think you’re okay but let’s make sure?
Strain: Jack Herer auto (Aussie baked beans)
Age of plant: 6 weeks
Method: Hydroponics (DWC)
Vessels: Bucket (16L but I only use about 9 Litres. Duel air stones)
PH and PPM: pH always around the 5.8 - 6. PPM always in the reccomended range for the grow stage( I had it around 750 before the flush) measured using a pH & PPM reader
Grow space: 90 X 50 X 1.6
Light system: LED. 1000w. Green fingers duel veg and bloom
Actual wattage draw of lights: unsure
Current Light Schedule: 18 & 6
Temps: day between 21 - 24. Nights about 20 - 23
Humidity: Day 40 - 50 Night around the same
Ventilation system: Yes
Dehumidifier: Yes. 1 litre
Temperature of reservoir: 19 - 21
TDS of nutrient solution: unsure
Hope that helps. I’ll be changing the res out today and post the pics
This is going to be a problem if it isn’t already. A larger amount of liquid will help to maintain conditions longer: in flower you will be changing and filling the rez daily. PH swings are also common.
If you are using a net pot I would strongly suggest, at the least, to rig up a larger plant rez. Black totes work well for this and are cheap. A 27 gallon tote would leave you with around 18 gallons of liquid to work with. That will buffer nicely.
