Last chance....

Hello good people.

First, let me apologize for my bad English.

I can't find a solution anywhere or the source of the problem I'm having so I ended up on this forum and decided to seek help.

The situation in the grow tent is as follows.

Foreign - Auto power plant

Lighting - Pure led 480W 25% intensity
Exhaust - VK 125mm 480 m/3
Intake - TT vent 100mm 280 m/3
Fertilizers - Advance nutritions

Humidity - 50%—60%
Temperature - about 20 degrees Celsius and I am not able to raise the temperature.

The plants have been in bloom for 3 weeks and have stopped growing, the leaves have curled and darkened.

I tried to reduce the fans inside the box because I suspected wind burn, but it didn't help.

I tried doing a flush 5 days ago but it doesn't seem to help.

I suspect nitrogen poisoning... I don't know what else to think.

If anyone has any ideas I would be very grateful.

How much of a flush did you do and did you feed them right after as a sudden drop in available nutes could cause growth to stall for sure.

It's pretty easy to wash out those AN nutes and the final part of the flush should be a good feed at about half strength, (2ml/L of each), so they have a balanced diet then the next feed heavier on the bloom portion. I like to feed Lucas Formula style after the stretch period using 1ml of Micro for every 2ml of Bloom with no Grow. A half dose of Big Bud along with that until mid-flower/ end of week 5 kind of thing.

Go easy on the calmag if you're using that too.

:peace:

First of all, thanks for your reply.

I did a flush on Friday 23.9 with 30L of water PH 6.8, at the end of the flush I didn't use fertilizer because I didn't know I needed it and I was afraid of making even bigger shit. Can you please help me how to proceed since I didn't fertilize after the flush . And am I right when I suspect nitrogen poisoning?

O yeah, i dont use calmag.

It honestly doesn't make sense to me that it is overwatering, the plants were watered every 3-4 days with 3.5l of water and the pots were very light when I watered. It's not burning on the edge of the blades, but curling.

I don't know the solution, but I will say overwatering can cause all kinds of issues, and it's not that you overwater just recently but that the roots stayed wet too long at some point. You could have overwatered it 2 weeks ago and are just now seeing the symptoms.

How big are your pots?
Try to cut down your time between watering, 3-4 days is on the longer side & try to reduce volume of watering. I water daily, with 1-2 litres for a 3/4 filled 5 gallon fabric pot.
The leaf drooping is right after watering heavy.

Wow, you overwater while underwatering, impressive. Roots won't move into dry soil much less so if it's become hydrophobic. You need to properly water the whole medium until saturation, then dry out until pot is light before watering again.
As you do these cycles, you'll water more and more frequently as her roots stretch.

Roots are not getting any bigger once you're in flower.
I'm fine with my water schedule for my volume stated. I have great roots and buds. I saturate my medium fine, runoff resoaks and nutes added near end of organic cycle. Over watering is a PITA, easily done by newbies without proper drained soil and you run into all kinds of issues.

Lol, what bullshit. Roots continue growing until about week 6 of flower.

Oh damn my typo, i meant 5 Litres, not gallons.
Damn US conversion.
The roots would have done the major growth in veg up to a little after the flip. Then it slows down major in favour of bud production.
