Is it mag deficiency there?

[ShroomShroom]

Hello,

Currently having this autoflower in 1 week 1/2 | 2 weeks flowering.
It's starting to show some deficiency I guess.

PH is ok.
Using Terra aquatica tri part + calmag at 70% recommended dose.
Lower leaf don't seem as much affected.

If it's a mag def, should i start using 100% recommended dose for nuts?

Cheers!

That yellowing does look like Mg deficiency. Increasing the dose could help. I don't use calmag, so someone who does would provide better advice. I believe I see indications of excess light, so reducing the intensity might help, too.

Hi!

Ty for your answer!

What makes you think of some excess light?
