Bottom Leaves Yellowing

[Meowza]

Hey everyone, I’m about halfway through week 6 and I’m becoming very concerned about the bottom leaves of my 3 Northern Lights yellowing and dying off. They started yellowing about 5 days ago, at that time I had probably waited a day longer than I should have to feed them so I figured they were just really thirsty. Watering with my normal dose of GH FloraTrio nutrients did not help and now the bottom leaves are looking pretty rough. Top growth is all healthy, but the illness does appear to be slowing rising up the plant. Looks to me like Nitrogen deficiency but I’m new to growing so I’m not sure. I would think that if it was a nute deficiency it would have gotten a little better after feeding, not worse. I want to water them today, please let me know if I should make any changes to my nutes, my feeding schedule calls for this:
FloraMicro: 4ml
FloraGro: 1ml
FloraBloom: 5ml
CALiMAGic: 2.5ml
All measurements per gallon, thank you for any help!

It's normal for a few older bottom leaves to die off due to lack of light.I would remove the bad leaves and you should be fine.
