FOG Auto seem short? + General auto question

Posted this is newbies but no one answered so here I am with n00b questions.

So I have a FOG Auto on Day 40

The info I have on this says it flowers in 75-100 days. At day 40 I am expecting it to flip soon. Question 1 is why does it seem so short?

I am 90% sure it's just because my LED tent isn't top tier. I've got a MarsHydro 600w (the old blurple kind, not their new white light..got my eye on it tho). And a Rapid LED 120w logic puck. Theoretically good for my 2x4 space, but obviously it's no Spectrum King.

My other thought is that I went too light on nutes. I definitely go light on nutes, which coulda bit me in the ass with the less-than-killer lights.

Question 2 is general. Do autos go through the same stretch period as photoperiods? If so, I think it might still do a bit more now that it's under the HPS.

Thoughts? Tips? Tricks? All appreciated

Lights: MarsHydro 600W + RapidLED 120W logic puck
Now under 600W HPS

Nutes: Fox Farm Grow Big [6-4-4] (1tbsp per 2gal in 6.5pH water every other feeding)
Couple hits of Microbe Life All In One [0.5-0.5-0.5] (2 tsp per gal for micro nutes)

Medium: Fox Farm Ocean Forest and Promix (about 70/30 ratio)

The HPS throws off the real colors but looks nice and healthy. My guess would be the genetics!
What was the distance you kept your lights at during the veg?

Thanks! I thought it looked pretty good too, which is why I was confused lol. I had one other auto run with the same setup and they vegged to be at least 32" before flower. I think this one is about a foot tall.

I had the lights pretty high! My MarsHydro 600W was like 3ft up. I kept the 120W closer to compensate so that was prob at about 20".

Also my bad on the light. Here's some better pics under white CFLs.

Is FOG strain name or the breeder?
