Is this nitrogen deficiency?

My Judy is two weeks from going to 12/12 and suddenly some of the lower inside leaves are starting to yellow from the perimeter and moving in.

All about judy is in my journal below.

Please can anyone help before this gets completely out of hand.

Many thanks to all who offer advice on how to save my girl. + rep

How long has it been in that soil, do you use nutes...looks like minor def...cal/mag.

If anything it is Nitrogen burn or maybe a little over watering.

Your plant looks super green so I seriously doubt it is N deficiency.

Here is guide to deficiencies and toxicities.

Judy is in a 12"x9" pot with a mixture of Miracle Grow potting soil (21-7-14), Perlite, and worm castings. I watered her two days ago with some "Superthrive 50 in one" 4 drops in a gallon (calls for 1/4 teaspoon / gal). She was repotted 25 days ago. She is just showing a few roots at the drain holes. Her light cycle is 18/6. + rep

I water her every 5-7 days once my meter tells me she is dry down at least 7" down and her pot feels light. + rep

Great guide. My problem is that I can't seem to match my issues with the pics. + rep

It is only on the leaves in the interior of my little bush but it came on suddenly and if I cant fix it I fear a complete takeover and an end to judy.

Those pics that pureblood put up should help you...I am sure of this.

When in doubt flush.

Yes, Flush,
She is in a 2-2.5 gal pot so I gave her a 5 gal flush.
Only had 3 gal O RO water so I hit her with two gal tap and followed it up with the RO water.
Got her up on blocks to drain well.
Will see how she does.
I flushed her 1/2 hour before sunrise (for her). Now the sun has flicked on . Time to get up N grow.
