Desfogliare

Ciao! Se le tue piante automatiche (autofiorenti) sono a 3 settimane, molto probabilmente si trovano ancora nella fase vegetativa o stanno entrando nella pre-fioritura. Ecco alcuni consigli: 1. Defogliazione precoce (rimozione foglie grandi): Non è sempre consigliabile farlo troppo presto con le autofiorenti, perché hanno un ciclo limitato e ogni stress può ridurre la resa finale. Le foglie grandi (le “fan leaves”) servono alla pianta per immagazzinare energia e svolgere la fotosintesi. Rimuoverle troppo presto può rallentare lo sviluppo. 2. Aspetta la fioritura: Il consiglio generale è di aspettare l’inizio della fioritura vera e propria (di solito intorno alla 4ª settimana per le auto), e solo allora togliere qualche foglia grande solo se blocca chiaramente la luce ai rami inferiori. 3. Tecniche soft: Piuttosto che defogliare, valuta il low stress training (LST) se vuoi migliorare l’esposizione alla luce senza stressare troppo la pianta. In sintesi: Aspetta ancora una settimana, osserva se la fioritura parte, e poi eventualmente togli solo alcune foglie grosse che coprono i fiori o i rami promettenti. Non esagerare: meno stress, più resa.

here is nothing in this picture that yuo should remove. removing leaves does not 'help' a plant. https://www.cocoforcannabis.com/community/photons_corner/to-defoliate-or-not-to-defoliate/ unlike most marijuana sites, this guy doesn't just repeat bro-science. it has good info. the comment section and forum is still a minefield of user-submitted nonense, lol. there is no evidence that supports defoliation improving anything. it's just something that got repeated so often it became a commonly held belief you don't have congestion. There is no pathogen risk. removing growth does not 'allow it to focus on buds' nor anything akin to that. Removing leaves will actaully cause more leaves to grow as long as vege growth has not ended yet. it can delay flower. It can cause excessive stretch. So many negatives definitely happen and nothing actually shows an improvement in yield or quality, lol.

Your auto’s big fan leaves are your solar panels, at three weeks let them stay. Wait for the first white pistils at the nodes (pre-flower) before you trim, and even then only pull a few leaves that block light or are yellowing. Autos hate heavy defoliation, so minimal cleanup just before bloom is safest.

I usually start defoliating around day 20, as the plant typically isn’t strong enough before that. I focus on keeping the lower third of the plant airy – lollipopping helps with that. However, each strain reacts differently to defoliation, and it always puts some stress on the plant. That said, you can definitely remove a few leaves here and there, as long as you keep a balanced approach.
