Suspected deficiency but not sure whats going on yet pics in post

[420growerUK]

Plant on left is perfect no signs of deficiency at all and plant on right is a mess dry Crisping leaves brown spots looks like N def but been given cal mag for 2 feeds now and getting worse, both plants share a res so both getting the exact same feeding and conditions etc only difference is that the plant with symptoms the air stone broke so its just the air line providing oxygen to the roots could this be the cause of my problems and if so surely a new air stone would solve this? As you can see there is a noticible difference between the two needi g to get this sorted out as just flipped to 12/12 any help is 100% appreciated

You can get a new stone but the stone just mixes the solution more than it adds oxygen. Are leaves yellowing at the top or the bottom of the plant?

Not really yellowing, more just lighter green with brown spots and dry leaves but leaves are staying green except showing leave veins like N def as I said tho the other plant is perfect my rh is a bit low at around 30-33 but never had issues before with low rh temps are fine only difference is the air stone

Could be something coming out of solution without the air stone.

I'm going to get another airstone and A/N voodoo juice for the roots but roots seem fine a bit discoloured but that's the feed and cal mag no slime on roots etc so voodoo is just to help things along and give the roots a little boost

We always run an enzyme cleaner of some sort, usually Z7.

What's that? What is it used for?

It cleans slime and inorganic buildup from your system, some use sensizyme or hydrozyme. Z7 is hands down the best.

Thanks for the info mate appreciated

Let's hope an airstone does the trick.

Is it flying skull z7?

 

[Pennywise]

Yes that's the one.

Not sure about the U.K. but in Canada it's sold as Z9
