I have some leaf spotting fungus i believe. I treated it 2 days ago and picked the leaves off. It says to use every 7 to 10 days (rose rx 3n1). Just dont want that to hurt my yield. What should my next step be?

I'd recommend using Neem Oil instead of the Rose 3 in 1. Neem Oil can be used in flower too, but I would not soak my buds with it, try spraying the affected leaves only. Good luck! :+1:

Yo i've been checking and double checking your photos ! good news man ! it's not fungus ! it's good news because at this stage of the flower the cure can be almost as bad as the ilness ! gotta keep those buds dry ! it s a bit of P/K deficiency from making buds... you can tell from the rust spots commen on. just add some boost or flower nutes and pray for yield, but you got a good one here, no stress!

Hi Greenthumb, your growroom is quite dry, your plants like to have more Humidity. the humidity and the temperature cooperate together. here i have a VPN tablau for you... you can always look in which stage which rh you need to have healthy plants::::::http://www.just4growers.com/media/23631/vpd_2degree.gif

Hello @Greenthumb4488 ! Are you sure it was a fungus ? It would be better if you had a photo... I am asking because your grow conditions are not vary suitable for a fungus that grows on leaves like powdery and downy mildew and your plant doesn't have a thick canopy so it has a good air movement. Unless you have humidity spikes at night time ( very common thing ).46 % RH at 31 °c can easily become 70 % at 24 °c which is your night time temperature. Since your plants are already defoliated and you can't drop the RH lower because your plants will suffer just put a fun if you don't have one and most important check the humidity at night time. If you have 24 °c then your humidity needs to be at 45% - 55 %.
Happy growing ! :facepunch:
