OK, I'm just trying to find a valid example of the nitrogen source being the deficiency cause, Nitrate vs Ammonia. In your case since you doubled the Nitrogen and changed the source it does not answer that question.
A few more questions so we can refer back in the future..
1.How long did you use K-lite before switching?
2.Why did you start using K-lite?
3.Before using K-lite did you experience problems with rot or plant loss or insect infestations?
4. After switching to K-lite did you notice less of the above problems/
The reason I ask these questions is because they pertain to the Potassium and Phosphorous part of the fertilizer ratios and whether these two componets are what contribute to poor plant health (obesity). You corrected a nitrogen deficiency by increasing (2x) the nitrogen amount and type. At the same time you have increased the Potassium and Phosphorous 1000% (10x).
Your plants look good!
