Lower leaves yellow

[CallumCush]

Problem, lower leaves turning yellow and dieing.
Seeds: RQS quick one
Soil: biobizz lightmix.
Water ph: 6.3-6.7 added biobizz calmag(just under recommend dose per litre) on 2 of the last 3 waters.
Light: Marshydro ts1000
Temps can fluctuate abit but roughly 23-28
Feed: livingsoils(UK company) top dressed. they had 1 feed of grow after 3 weeks,which had slightly to strong N.
And a feed of bloom 3 days ago at beginning of week 5.
Reading around most websites and forum's would suggest N deficiencys but I would like someone's opinion first from the pics.

I would say she is hungry and looking for more N. Whole plant looks light green, and the yellowing from the bottom up also points towards the lack of nitrogen.

Thanks. Just what I was looking for. My first grow so i didn't want to go throwing nutrients at her if she didn't need it. Will top her up and hope for the best.
