This one has got a little unhappy. Seemed to happen when i added extraction fan for around 24 hours on sealed tent. Had quite a lot of negative pressure, nut sure much air was sucking in through any gaps.
When I noticed the issue there was also some kind of air movement happening as this one was swaying in the 'wind'.
Anyhoo seems ok ish since i turned off the fan, ill need to sort some inbound and outbound fans to prevent too much neg pressure.
Am i good to snip off those leaves or.... should i leave, defo getting worse. It was only on the middle part of the leaf to start with. Dont want them affecting the rest of the plant.
Cheers in Advance
