Should I up my cardio vs stregnth?

If you are eating 1000 cals per day with that amount of activity honestly it is a recipe for disaster.

You may be ok for a few days or possibly even weeks, but there will come a time that your body will fight you. It may result in deviating from your diet (possibly with a binge), it may be a lack of energy, deterioration of health etc.

It's going to be difficult to give any more advice without being able to see your diary/stats etc, but I would certainly advise you to eat more.

I started my workout routine 5 weeks back. I have taken rest days 1/week and on 2 occassions 2/week. I have lost 2kg (4.4lbs), but due to water retention or for god knows what reason, I mostly see my starting weight on the scale. I did not take my starting measurements, but my clothes are lose or fit well. So, I know there is loss. I would really appreciate if you share your opinions on 1) whether I am doing less cardio 2) I am on track 3) I am not eating right. I really want the scale to show me the money!!

Here is the breakdown of my 40-60min workout routine and food intake.
Stregnth 3x 30-45 mins + 15-20 mins cardio after (light)
Spin class 3x 30-45 mins + 15-20 mins treadmill/cycle (light effort)

Consuming approx 1,000 cals/day; I meet my carb level; almost meet my protein and am way below on my sugar intake most days.

Hi - here is my tuppence worth. A safe DAILY NET deficit of 500 to 1000 is USUALLY optimal. Too big a deficit for too long can introduce hormone issues. If you are only eating 1,000 and doing THAT work out along with your basic metabolism,you may have a daily deficit of double the high end. People can become catabolic in these conditions so would advise caution here.

I would also argue that in this early stage of workout, while it is hard to gain muscle in a deficit, you will be toning muscle. muscle is denser than fat so there is a CHANCE you are losing fat but not seeing it on the scale as you strengthen muscle. Clothes are a good indicator of this - as is a tape measure and a mirror or photos. I find if I track using 3-4 methods, I am more assured of progress or regress. Scales are only one way and they CAN be incredibly innacurate.

Your workout schedule is aggressive so if I were you I would either keep the diet as is and cut BACK on the routines, or kep the routines and add 200 to 300 calories a day for a week and see what changes this brings.
