There under a 450w led light
Does this look healthy

So 200 real watts then
"Comparable to traditional 300W HPS/MH while consuming only 200W!"

Look a lil over watered aside from that they're fine

That light aint equal to a 400w HID/Hortilux HPS.
#1 for an LED to be comparable to the best SE HID is one needs to use the best diodes available. Samsung 301b-h. from what I understand they are the same, but H may be more resistant to humidity ect. Better outside coating. Slightly more efficient. Osram has the best Red/Far Red LED Diodes.
That light uses Bridgelux, and are not as efficient vs Samsung, so one cannot compare it to industry standard as Vivaspectra is outdated. Not saying it wont "WORK" - lots of crap works, but is not optimal. We grew some killer weed back in the 70s with 8ft Super High Output fluoroescent, but it also took forever. Mel Frank, and Ed Rosenthal started with fluoroescent in the 60s.
The best LED diodes are basically 33%-40% more efficient than SE HID. 600w-650w is equal to a 1000w SE-HID using the best diodes, and diode placement configuration.
Phillips probably makes the most efficient LED, but they only sell in lots of 40. $800 each in quantity, which is a killer price, but few have $32,000 for lights. Toplight Compact
630w, and 1800umol
To me plant looks overwatered, container is to small, not enough light/good light. Dont like how the leaves are drooping. Also could be the medium is to heavy?? What is Medium???
Never let it get completely dry. When they get that dry, you concentrate dissolved solids, and when watered, rehydrates the concentrated dissolved solids, increasing the chance of burning them. Is a double whammy if they are fed again. I like to get a cheap Moisture-PH-Light Meter from Lowes, and use the moisture gauge, and NEVER let the needle go under Low Moist. Really low moist granted, but NEVER to the DRY Line. I measure in several locations depending on container size.
Plant may also benefit from more fresh air flow, and a slight breeze 24/7, regardless if lights on, or off. I veg 24/7. I turn light out 3 hours every 3 days to rest ballast/ignitor. I use 1000w HID/Hortilux for seedlings-flowering.
For LED to equal SE HID one should strive to get 42.5w Sq/Ft with the best Samsung/Osram diodes.
SE-HID strive for 62w-sq/ft.

I decided to go the cheap route thinking I'd just be small scale for the foreseeable future (not happenin), hence the Viraspectras.
Anyways... I have the Viraspectra 300w. The 450w is arriving tomorrow.
My 300w at 23" from plants dead center gives ~18k lux.
25lux at about 18".
Move past the footprint of the fixture and it will drop to 11k lux. More than ~5inches outside of the foot print and you don't want a plant there.
I need more light. I want all my plants getting 30k+ lux.
