Plant looks healthy but for week 4 you should be a lot bigger
Edit noticed you cut it all.maybe do some lst you would get more without losing tops.only downside its not gonna be all same height

It's a healthy plant and it's great that you've topped it. That will make it much easier to light property.

I agree with @amneziaHaze about the size of the plant.

What's your PPFD and your light schedule? If you're not measuring light, what model light, hang height and dimmer setting?

A lot of growers use 18/6. My preference is 24/0 but I also do 20/4. Cannabis does not need darkness to do "dark cycle" processing. That's a confusing term for the Calvin cycle.

Below is a picture of a photoperiod grow on day 24.

Here's my lighting data.

The XS-1500 is the original light from Vipar (not the Pro) and the X2 is a Growcraft veg light with two light bars.

23= day number
3.2 is week.day

560=PPM (500)
57 is pH
492=PPFD
37.2=DLI

VPD was probably 0.8 at that time, wind at about 1 meter/second, res temp 68° (chiller)

If you're in hydro and have similar conditions, you should be able to use similar light levels and get similar results. "similar" is key there because the light in the picture is a veg light and the blue photons will make the plant compact. Some grow lights have a lot of blue, some are more red-heavy but the biggest driver of growth is the number of photons hitting the canopy.

Growth really took off on day 26. The photo below was day 29.

Looking back at the data now, I increased PPFD significantly after day 21. Plants respond quickly and in an almost linear manner to increased light levels. I can't see that the increased DLI caused the increase in growth but it certainly was a factor.

Nice healthy looking plant for your 1st DWC grow. Plant might be a little small for week four, is that time from sprout or up and clear? Also what is your air temp? Might be a little chilly.

Looks healthy....I would also suggest raising temps a bit. Low 80's are best with led while in veg.
 
She is a. Bazooka punch started. With seed I'm running a mars hydro ts1000 150 wat in a 2 by 2 diy closet temps stay in the 80 and 70s at night. I'm doing res changed every few days to hopefully prevent root root. Light is roughly 14 inches from plant. I'm using genral hydroponics fluro with southern ag for root root

It was from me putting in the dwc setup. Had a taproot out the bottom. I'm new to this but seems to be going ok. Not sure if usual growth rate. With dwc

Nice light! Nice job too. I like my mars hydros. Oh I see you have the same model too. I use them per 2.5x2.5 feet just a fyi mars hydro suggests they can. Lights that size are harder to find.

I boiled it down to like 2 models 2 brands but Im sure there are lesser known name brands out there.
