Hey rollitupers lol. I have some yellow spots appearing on one of six plants in the same reservoir. They are growing in an aero system under a 600 watt hps with adequate ventilation. Temps rarely get above 80. They are all autos but this is the only one that is berry bomb. The are being fed A.N. ph perfect trio with b-52, piranha, and voodoo juice as additives and A.N. cal-mag. They are almost to flower. Ive tried top include a much info as i can think of at the moment. If there is anything else you need to know just ask and any help is really appreciated.

What do your roots look like??
If your roots, and reservoir temps are fine, I'd be sus on too much calcium. Judging by the dark leaf edges.
What's the calcium% in your base feed, and calmag combined? Nitrogen too.
Check your roots, and chamber temps first.

Not sure about res temps honestly but it feels like room temp. It's not hot but not cold either. Roots are a nice white color. To much calcium makes sense bc last time i added cal mag i felt like i may have been adding too much

TBH
If your reservoir is sitting at room temperature that's a major contributor to your problem. I'd be getting the reservoir temps down. Ideally you want your root zone no less than 65, and no more than 70. Black edges like that are quite often the first signs of low oxygen. Rot soon follows.
The warmer water is, the less oxygen it can hold. All that O2 is escaping straight into the tent / grow space.

I think the right plan forward is-

1. Get your reservoir temps under control ASAP. Use ice, an aquarium chiller on a thermostat, or WTF you need to do, to keep it between 65 and 70.

2. Cut out your calmag, for a feed or two. See if it improves.

IMHO keep your room temps the same. 75 - 80 is just right during lights on. Veg or bloom.


Good luck.

I find those reptile thermometers pretty handy too. You can just sit the thermometer in the reservoir. Then have the display sitting outside your reservoir. That way you can view your temps without opening the reservoir.
A lot of them come with hydrometers as well.
They cost $10 - 15 bucks at petbarn.

Imho, you're eventually gonna have to invest in some method of cooling. Ice won't keep the temps down for long.
Adding ice all the time is going to be tedious too.

It's not the spots that are a worry at all.
It's the black leaf edges, and is a very tell tale sign of things to come, if the reservoir temps aren't fixed.
A couple spots on a leaf, who cares?
Black leaf edges is a different story.
:peace:

Ignorant, unhelpful, dick wit.
Room temps are fine. Humidity would be fine.
No cooling for the reservoir. Room temps up to 80.
What do you suggest it is besides an oxygen issue???????

Please help the OP. instead of being a little bitch and hassling me!

NO!
If you have 20 plants in a recycling system, do they all get sick at exactly the same time??
Plants have individual immune systems too. Some get sick before others.
I've never had all plants get sick at the same time. Unless I've fried them, with nutrients.
