Unfortunately, my autos are 20, 30, shit, mine are always small......
I don't grow autos, I play with them.....
So on to the seriousness.....
I know, from past experiences and reading/studying these plants, that there are so many variables.....
Not knowing about your grow, I'm wondering about your watering habits....
Hear me out......I'm trying.......
Do you gradually water/feed super slowly, so that the medium is totally saturated, from top to bottom.....for a fact?
Reason I ask is.....are the roots searching and digging and growing towards the bottom nicely....
Are you vegging long enough for the roots to develop " fully ".......
My plants are usually small because of room restraint.....gotta keep um tiny in veg, then when my bigger area is cleared, in they go.....then they can do there thing......
It looks like the light it off to one side of the plant, usually "praying " is uniform with both leaves, however I think you could safetly turn the light up a bit, just read how she reacts. If the leaves start getting a little droopy, looking like it's overwatered a touch, then dial It back, otherwise you should be good happy growing
This grow is way over and I'm working on my photo's for outside. I found the mars hydro manual. They suggest 12" at 25% for seedlings. 12" at 50% veg. 12" at full in flower. I didn't feel comfortable with 12" so I went 16" above. I'm now in veg at 50% light. My plants are looking good. 50% is about 225w. My first grow never got over 75 to 100w.

I know a lot of newer growers use the manual recommendations and end up with issues.
Even though I don't like some of Vivosuns business practices, there light hanging recommendations in the manual is better then any other manufacturers recommendation I've seen.
Notice how they say "this is reference only and to adjust to your actual situation".
This is pretty close to how I run both my VS4000 and the Spider Farmer SE4500. I never get closer then 18" in flower though.
As far as dimmer settings, In Seedling and Veg stage, you will never see my lights over 40%. In flower I will ramp up each week until I'm at 80%-100% power (if plants can take it) and let it ride for 3 weeks and then start decreasing light intensity to the end of flower.
Here is the recommendations from the Spider Farmer manual for my SE4500.
I currently have my lights pretty far from there recommendations, I'm in veg sitting at 40% light at 30" high and this is what my plants look like.
Strange? No. I've thought for a while that light power is oversold. That may be good, though. I've reconfigured my tents several times, and it's nice to have flexibility in moving lights, even though I've never run one at 100%.
