Powdery mildew thrives in over-watered and overcrowded plants and high humidity environments - which is why it's important to keep clean air circulating. Implementing HEPA grow room air cleaners will actively remove dangerous submicron particulate to prevent WPM and other molds from coming into contact with your crop.Best of luck

Powdery mildew will kill his grow and he needs to act quickly! There are a few home remedies that work fairly well on his plants:
Milk Spray ( 10-12oz per gallon of water, 1:9 Ratio)
Hydrogen Peroxide 35% (1 tsp per gallon of water)
Baking Soda (“Sodium Bicarbonate” 2 Tablespoons per gallon) or
Apple Cider Vinegar (2-3 Tablespoons per gallon of water)
These are used as either a spray or surface wipe-down..
He should also THOROUGHLY clean his tent with one of these solutions (for MY money, the hydrogen peroxide is the best and btw, tents should be thoroughly cleaned between harvests)... and then definitely get the humidity under control, and good air flow going. And btw, powdery mildew will NOT go away on it's own so tell him if he wants to save his grow, he needs to act NOW...

Bad air circulation, and too much humidity can cause that if it's not to bad then it can be saved with vinegar with water. Works like a charm. Best of luck 👍

Flower LightDo you think this would be a good flowering light (on a budget) for a 4’x4’x80” - 1000 watt (5 plants - indoors - all hybrids ... if that matters)

Friends need your help! pH 6.2 EC 0.7Please help me understand what is the matter because of what dry tips? At first I thought it was all because of the light! but the light raised high and reduced power to a minimum! then I thought that the fan was too strong but I put it so that it would blow into the wall

Your opinion? Slow or Ok?What’s your opinion about this grow?
These autos are in their 9th week now!
Supposed to be fast ones, but they could easily need 4 more weeks or so?!
There are 8 plants in this custom made grow room of 1.20x1.20m with a Niello M-900 led.
I know every grow is different!

Reflecting on 1st grow: when should I have started pinching the side growth? There are lots of small buds on thin branches that are not going to develop as much. I thought that leaves help plants grow, so probably I kept too many of them. What the basic wisdom on pruning?Leaves. Too many
