Aurora Innovations Master Feed Underwatered and slight Nitrogen deficiency?

Hey guys,

This is my first grow and things have gone pretty smoothly up until this point. I am using Aurora Innovations Master's pack for nutrients, and am trying to get dialed in.

Last Saturday, I gave this plant a full feeding. She is very bushy and in a 5 gallon fabric pot. I gave her a little over a gallon with:

1 tsp Buddha grow 2-.25-1.5
1 tsp amino-aide 5-0-1
1 tsp trinity .1-.5-.25
1 tsp ancient amber .1-0-0

I should have watered yesterday, but the smaller ones weren't quite ready, so I decided to put it off until today. Bad idea.

She definitely looks very underwatered. I panicked and immediate watered with another gallon of 6.5 water.

I then continued to examine the plant, where I noticed slight signs of a nitrogen deficiency in the oldest, lowest leaves.

Could this be from the lack of water, or do I need to up by nutes? I was under the impression that I should be feeding only once a week and using only water in between.
Since this is such a fast growing, bushy plant should I be using nutrients with every feeding, or just more with the weekly feeding?

The smaller ones still look just fine, but I would like to get these nutes dialed in before the same thing starts happening to them.

lol I took matters into my own hands after referring back to the Cervantes grow bible. I gave a litter of mild nutrient solution and also top dressed with the sample dry nutes. These things are full of fast acting nitrogen sources. I should see full recovery in 5-7 days. Just gotta make sure I keep up with them, especially under the COBs
