If you're already adding Mg it's likely enough, it's probably running into absorption issues. The first and third pic look like Mg but the second more of a lack if N. I bet you have salts building up in the rootzone. Pretty common issue around midflower that often gets misdiagnosed as a deficiency. Collect some runoff data and if that's the case give her a good flush.

Northern lights with yellowing leavesHey Guys, my NL is starting to have some issues.
I started off with the leaves just laying low, i've eliminated lack and excess water, and it's not temperature related.
I did a small flush 3 days ago and things got worse.
What do you guys think?

Is this normal new leaf color growth?It seems again that my leaves are a touch shiny, slightly curled down, and are a touch yellow. I water only 1 Liter every two days and do not use any fertilizer apart from coffee grounds and aquarium water which has slight minerals. Thanks for the help in advance

Leaf problem and purple stemsHi,
I have a problem with my auto.
I have purple stems and problems with the leaves.
The soil contains organic nutrients and mycos sometimes I add flowering boost from royalqueenseeds so I don't think it is P or K problem.
Is it a nitrogen deficiency ?
Thank you for the answer
