Nighttime droop

This plant sprouted five weeks ago and is 24” underneath LEDs with 50 percent humidity and temps around 78 during the on cycle. I’m feeding it Jack’s Blossom Booster at the recommended 1/4 tsp per gallon every day, plus occasional a bit of seaweed fert. It looks fantastic during the day but droops like this each night (18/6 on/off).

I’ve seen where sometimes they droop at night but this seems pretty dramatic. It’s in a three gallon sack and I water it until it drains out the bottom every other day.

Is this a sign of anything serious, or, can I just ignore it since it’s perky and robust in the daylight? It’s not too dry and it does this whether I’ve watered that day or not. I thought it might need more nutrients but I’m seeing small spots of nutrient burn here and there. Thanks. 126E76EF-3E65-4579-B68B-CF6F9F646011.jpeg126E76EF-3E65-4579-B68B-CF6F9F646011.jpeg

I'm gonna second overwatering. I like to go by weight, ex: water the plant till some runoff occurs, lift the pot up or tug the handle to get an idea of the weight. Check the weight like this every day until the pot is light & very easy to pickup. This works for me from 3 gallon to 20 gallon smart pots.

Thanks all. The light is a spider farmer sf 2000 led and the tent is 2x4 with two plants. Only problem I’ve had with the light is constantly fighting heat gain and having to run it at 80 percent max. I will cut back on watering.

Put a fan blowing over the driver and board.

Overwatering and underwatering look very similar, I would have to say it looks underwatered to me, due to the fact that the leaves are not curling in on them selves, I always thought if they are overwatered the leaves look limp and curl in on them selves, I don't see any curling on the leaves, they just look limp like it's underwatered. I'm also seeing yellowing on the bottom leaves which is a sign of a mobile nutrient deficiency

What happened to me which was confusing af was my pots used to dry out (fabric pots) but my plants still looked like that.

Turns out I vegged the plants longer than anticipated and thus they must have gotten root bound. Yes i know - a fabric pot! I then transplanted into a bigger plastic pot and they are healthy as ever now.

Thanks. Did you simply drop the fabric into the bigger pot and surround it with soil? I’d hate to screw it up more by digging it out.

Yeah what you do is let the soil dry out as much as possible. I then used a bread knife to cut down the sides of the pot (not cutting the pot - cutting/ separating the roots from the sides of the pot.

Then I pushed them out from the bottom, once you get the root ball out you put it into a the new put but with soil at the bottom. Gotta make sure the stem aligns roughly with the top of the pot

I used to do it this way but now I transplant wet, (around 24 hours after watering) when you transplant dry, the soil around the roots become loose and it can just fall apart. From my experience it's best to transplant wet And I just tip the plant upside down and slowly loosen the soil around the pot and it just falls out of the plant pot all in tact with no dusty soil/coco :)

Thanks both. A little leery of digging into it as this is my first indoor grow. It’s a three gallon sack and the plant isn’t that large compared to its sister who is doing fine in the same pot. There are times when this hobby can just sick my fat ass lol.

I'm 100% sure it's underfed due to the yellowing on the bottom so I would definitely recommend upping the feed, that should help her out :bigjoint:

I agree. Overwatered leaves have a shit ton of turgor. The leaves in the pic look lifeless.

Thanks once more all. These aren’t the best seeds as they’re from ILGM and while they are auto, I don’t trust that they’re actually Northern Lights. The two plants are from the same lot in the same order and one is more sativa and the other mostly looks to be indica (the one pictured). Idk if poor quality seeds explain this but I’ve seen others complain about them.

Re over vs under its a split vote on here and I’ve tried both cutting back and then ramping back up the same thing happens. Only in the night cycle. Weird stuff. I’ve tried the going by weight approach and thought I had the system down but maybe not.
