Switched from 18/6 to 20/4 mid flower northern lights auto single blade leaves developing

Tassie grower · Jan 6, 2024

I switched from 18/6 to 20/4 due to high humidity during lights out and one of my autos is growing g single blade leaves out of the tops, should I switch back or will that stress her out even more? I have 3 other autos in the tent and a other one is doing it as well but not as bad

Single bladed leaves is part of normal flower development, and has nothing to do with changing the light schedule.

How did changing the lights affect the humidity though? You want humidity at about 55 for the stage your flowers are at. And if it's too high it needs to come down or you'll run into issues with bud rot.

The last picture looks a bit like light issues. Too hot, too close, to something. look at the edges of the leafs.

Humidity didn't change much, still 60 to 62 got a dehumidifier that is to small, waiting on a 25 litre for lung room about a week away
