I’m getting these brown and yellow leaf tips again. Last time I thought it was from a fungus potentially from dust so I bought a new carbon filter and ducting and cleaned every inch of the tent thoroughly.
The carbon filter cover is already covered in a thick white dust and the exhaust fan is barely blowing any air out.
I vacuumed the cover and now the airflow is normal.
Why is the cover getting so dusty? The only thing I can think of I got a new humidifier and it’s pretty humid (65%). Or maybe the room is dusty? There is a slightly opened window right next to the tent and I just have the ducting next to that. But at night it gets too cold and I have to close the window. Is it the air in my grow room that is dusty?
Anyway should I clip off the tips that are brown or just leave it?
I’m using 5 gallon air pots, strains are gelato and Girl Scout cookies autoflower, I’m downing a 24 hour light cycle and using organic dry amendments.
Calcium and mineral deposits from tap go all around the house. I have a son with asthma, and constant use of a humidifier using tap water, everything gets covered with water vapor (humidity). You only see it when it dries up.
The reading glasses I leave in my grow room get covered with calcium dust. The cost of distilled water would be prohibitive at this time - and spring is coming, with it’s attendant humidity. Yesterday we had a freak day at 79F with thunderstorms, and the humidifiers hardly ran.
And this is with my main tent venting outside. I always figure calcium is calcium, right?
