Possible MG def? Not sure though?

[Welshgrow]

Evening thc!
I posted this in my diary as well but there’s not much activity over there.

I’ve noticed some marks on a few leaves on one of my plants. I think it might be mag deficiency? Not entirely sure though as the she still looks pretty green.

Here’s the details

She’s an auto around 28 days old
Canna terra pro soil
20l airports
No nutes yet just rhizo and bio silicon
Tap water left standing for 24hrs,
Getting around 2ltrs every 3days.
Lights 24/0
1200w hps
Temps around 23-26 depending on time of day.
Humidity around 36

I’ve think that’s everything??

Here’s the pics


Thanks for help guys.

How many plants mate?

1200w is hard to keep nutrition up. Spots look calcium related

Yeah seems a bit high that, if they are this sort of size. Dropping a bit of light will help a lot.

It could just be a sign of needing food in general? What do you have for bloom

They started off rich, hence dark leaves but she's leaning out towards the bottom

I got some canna Flores for bloom but they ain’t had any yet,
I also got some plant magic magnecal from my last grow aswell if that’s any good?

Do you think I should dim one down to 400w or even 250w as the 6 autos are all around this size.

Yeah I'd agree. Looks Calcium related to me as well. Hit em with some Cal mag and some bloom wouldn't hurt to give those buds a Kickstart. That Canna Terra dumps a Lot of N though hey? She's fucking darrrk lol

I would say too much feed or too strong soil causiing slight lockout of micros

Look how dark them leaves are . But the top thin sickly leaves showing iron or sulphur def . Usuallly caused by too much phosphorus

This an auto ? They are more delicate feed wise .

Dim em both to 400 and see how they respond. If they've had no feed yet then I'd start them off on flores. You can add a splash of magnecal too

Cheers for the replies fellas!!

Yea I dropped the lights down to 1x600w and I’ve got a 250w invisible sun board on Ed way so I’m gonna throw that in there as well.

On the feed front they each had 2ltrs made up with 2.5ml rhizo, 1ml canna boost and 2ml canna Flores.
That was 2 days ago and it doesn’t seem to have gotten any worse, so fingers crossed they were just hungry.
Gonna pop my head in later and see how thy look so if they gone bad I’ll be back haha!!

Thanks again

Here she is tonight.
She looks a lot better no new marking or spots on her just a nice shade of green not too dark.



Thanks again for all the help peeps!!
