Hi my brother's and sister's!
I have a bit of o problem and don't know way I have it.

So here some facts:
Light= LED spiderfarmer 1000 (100w if fully turned upp),
I use like 80% lighting power, 24h On al the time.
Growing medium soil = BioBizz Light
PH 6.6
Pot= 25L
Humidity = 53-57%
Food = BioBizz line

Did not test the run off yet but i will when i water it again and thats tomorrow.
But still it looks like potassium deficiency to me, what do you guys think it is?
Appreciate the help :grin:20220920_133658.jpg20220920_133732.jpg20220920_133728.jpg20220920_133711.jpg20220920_133704.jpg

Is it a soil grow? Are you letting it dry out between waterings? If you water too often, your plant will show symptoms of a deficiency even if the ph and fertilizer strength are adequate. I would check this thread out, it is old but there's a lot of good info to be gleaned from there. https://www.rollitup.org/t/plant-moisture-stress-symptoms-and-solutions.150004/
Plants grown with led lights need more transpiration via warmer ambient temps and more air circulation from fans. New growth looks twisted and light colored to me, a problem that if caused by watering too often can be fixed by watering less often and/or less amounts of water at a time. Most "cal/mag" deficiencies (misnomer, cal and mag are separate elements) under led's can be fixed by a better watering schedule in my opinion.

Biobizz “ light “ needs heavier feeds in it to compensate- this soil mix is more like a seedling mix ( very light on nutes ) . Looks like at this stage most of the medium probably began to tap out since you are using it “ long term “.

I would throw a feed between 900-1000 ppm / 6.5-6.7 ph at it. I doubt the original “ light “ buffering is still there and is probably gone. Tap water would cover the cal and mag issue too. You have purple stems and pale leaf.

BTW - 100w max is still not enough for plant either.

Biobizz light would have been better suited for small plant starts and germination cups.

U got a few issues going on. 1st off I cant believe noone called u out for running light 24/7. Plant needs its rest even if its an auto. Atleast 4-6hrs. 2nd like said earlier it is overwatered and 3rd it is hungry.
How far is that light from tops? I've seen gd results with that light with 1 plant or in 2x2 grow but turn it all the way up. U can't give it to much par or ppfd unless u closer then maybe 6-8" with only 100watts. Just my opinion. Happy growing!

Because it's an anthropomorphic view with no basis in science.

True but u don't believe the plant needs rest? If not then wouldn't it save money on the electric bill. Thats math! Lol

There is a point of diminishing returns with light duration and it makes perfect sense to run less than 24 hours to minimize electrical consumption.

That's a very different reason than a misplaced notion that the plants need a nap.

Plants don't need rest; it's not a belief, but an established fact.

Educate yourself a bit on plant physiology; a good suggested start:

Cannabis is a C3 plant. It uses the CO2 it gathers during the light period, when it is photosynthesizing. Plants designated C4 also gather CO2 during the dark period for use during the light period. Many C3 plants, including cannabis, do not need a rest period.

Most growers believe in “ rest periods “ . I do 20/4 upfront for VEG ( giving it as much energy needed ) to get the best growth before it decides to transition to flower. Then after stretch i drop to 18/6 til finish.

Both cycles protects my lights over plant. I would rather have my gear resting over plants. Last longer.

Are you sure you're giving it enough water? Even if you're getting runoff the rootball may have gotten a little hydrophobic...

So u agree not to run light 24hrs but not because of plant but cus of light and diminishing returns? Either way. Yes u can technically do it but what about metabolic processes that occur during dark period. What about 24hrs stressing your plant? They also say night is when it does recovery from any issue. Only certain ruderalis do well in the wild with 24/7 light. It was just my recommendation to give it some rest. If yall think he should leave it as-is cool. Folks can grow as they please. Ill put my 2 cents else where.
I even give my clones a rest but thats just me. Anyone else here use 24 hrs of light or just him? I would love to see some grows that do this. Not cus of disbelief but I want to see results. I dont know it all so im here to learn and share what I've experienced.

I like to rest 6 hours on clones and plants but I will leave them lit 24/7 when I drop a reveg in the mix
Not really scientific but I feel my root growth increases with some darkness :joint:

Science can only get u so far. Kind of like book smart vs street smart vs common sense. Just like people some plants are finicky or just don't play/act how they are known to. Then u adjust accordingly. Long as they are healthy and respond well to your grow style nothing else matters. I wouldn't raise my child by what a book told me. I would consider it tho. How many times has science recanted a previous scientific fact after further research or more knowledge comes to light.
