בעיה בתקופת הגידול

You appear to be suffering from water issues. I would be will to say I think you substrate ph is close to out of range or out. Which stops the plant from drinking, and causes deficiency signs from the lock out.

That looks super thirsty, your feeds are gonna go up in volume with size of plant and other conditions

I would say it's overwatering. With underwatering, the leaves would curl weirdly when they straighten up after watering again.

No diary = no information - sorry! It might have been watering problems, it might have been root fungus, it might have been a very bad infestation of fungus gnats... but there's no way to tell if you did anything wrong because we don't know what you did. That's the value of a diary on this site... it helps us help you. Next grow, start a diary! We want to help but we need information! Good luck....

Looks thirsty to me. Either you have root problems and she cant uptake enough water or your not watering enough. droopy leaves with straight stems = over watering droopy leaves with droopy stems = under watering

Okay, so it's a watering issue. First of all, thank you very much. Now I need to prepare a new one, or will it recover and show signs again?

Check if your soil is wet or completely dry. If it's too wet, I would let it dry out once. If it's too dry, of course, water it. But it looks more like it has too much water in the soil. Skip watering the plant for 2 days if the soil feels damp when you touch it...

Is there a way to handle this?

Looks to me like over or underwatering, drooping leaves without major signs of deficiencies... I'm no expert, but my plants look like they either didn't get enough water or got too much of it...

I watered according to the biobizz dosage, everything written at half the amount of light for 18 hours during the growing period and a normative distance of the lamp. I used Grow, Bloom, and in the last two weeks also Top Max. The pictures I uploaded are already after the flush I did with Revive. There are two small fans in the grow room. 60-60-1.50 There's an exhaust fan, and I always make sure to ventilate as well.

No dairy and not enough details to answer your question also better picture would help. Make a dairy and update regular with picture and equipment ect Sorry I can't help more
