Can anyone help me to identify if there is a problem with these plants from these pictures? I am not sure what is going on with the leaves.
Thanks in advance :)

• Northern Lights
• Growing from seed
• 16 Days since germinated and planted in final containers
• Estimate 7cm tall
• 11 Litre containers
• Medium is Biobizz light
• Water roughly every 2-3 days (when soil feels dry), use purchased bottled water
• PH is 7 from the source, brought down to 6.2 -> 6.5
• Biobizz Biogrow (2ml per Litre),
• LED lights, set to 300 watts
• Roughly 15-16 inches from plant tip to lights
• Growspace is 4Ft x 2Ft
• Temperature is mid 20's and humidity is just over 52% now
• Soil PH is just 6.2 - 6.5
• Have not noticed any insect activity

The first leaves cupping curling up abit is normal, but that leaf damage is not, obviously but....my input, as I'm not 100% certain exactly whats causing the issuue but temp bit on the cold side, for the plant and more than likely the roots , she also looks pretty hungry so I'd up the dose to 3-4ml a litre everywatering and make sure PH is infact between 6 - 7, and water in well...im still thinking so that will do for now.

I am going to take a stab at this by saying perhaps the lights are too close. (LED bleaching) Back the light off to around twenty to twenty-five inches away from the top of your canopy. If you are misting, try to mist them twenty minutes before lights on.

Come back in a week with progress pictures. Don’t try to many things at once to fix an issue because you won’t be sure what worked or didn’t. Let them veg longer and observe. At this stage they need almost nothing other than the right lighting/distance and humidity temps dialed in properly and water.

I don't know what those white specs are from but that does sound like a lot of light. And I think that Biobizz has barely any nutes. They definitely look hungry.

What does LED set too three hundred watts mean?
Click to expand...
The led lights at 100% on the dial are equivalent to 1000 watts. I have the dial at 30% so emitting equivalent of 300 watts. Definitely does not seem too hot under the lights but as mentioned (I did not realise) could possibly be some bleaching.

It almost looks like thrips or leafminers. I would check the underside of your leaves with a flashlight and magnifying glass at night, and see if you can spot any of the tiny little bastards. A blue sticky trap is really effective for thrips, but if you can find a yellow/blue bicolored sticky card, it’s even better because you can monitor for other pest species.

Overall the plant seems to be doing okay, despite the apparent damage.

I was wondering about thrips myself but didn't mention above as I didn't want to influence anyone's opinion. Have ordered some sticky cards there now, will use them regardless.


Everyone is so helpful, thank you all. How do the plants look hungry, what is the telltale sign of it?

Also, should I use Biobizz Heaven, Fish mix and Acti-vera alongside the Biogrow as per Biobizz nutrient schedule in light mix?

That light is a 130 watts actual on 100%
You might be able to do one plant with that
There is no good reason to turn it down
I asked because your plants look starved for light
I wish you well but your decision to use such a small light makes it challenging to accomplish a complete grow

Try downloading the Photone app on your phone and measuring the actual light at the plant rather than trying to go by watts. Or even a lux meter app.

Watts is a bit meaningless.

On photon app, at the canopy:
PPFD is currently 250 and can go to 1000 or there abouts.
Lux is 13,000 and can go to 45,000
DLI is 9.0 and can go to 45

Any idea what I should aim for ?

I was under the impression that the draw from the wall is 130watts but the LED equivalent is up to 1000watts at 100%..

False advertising industry wide
The truly exceptional lights advertise their actual power consumption and compare it to HID lighting
Like 740 watts actual is quite likely 1000 watt equivalent
The don’t hide actual wattage
Sorry you have been mislead
