Hello fellow gardeners,
my White Widows are sick and I fear they won't make it. They seem to have a severe infection from bacteria, but I also cannot exclude a fungus infection. I may have overwatered them, especially when I thought I had given them too much fertilizer, so I rinsed the soil.
It all started with brown stains like shown above. Then the leaves got burned from the sides (see next picture). Also, the plants started smelling less than before and they grew very slowly.
It got worse before I decided to cut off all affected leaves. However, the disease came back quickly.
To the day, I find stained leaves every day. The upper leaves also started loosing their healthy green color again, turning yellowish. The tips of the leaves are reddish-brown. There also are holes.
The only good news is: the red leav-veins turned green again after the last watering with fertilizer. However, the plants seem to have almost ceased drinking water by now.
Is there anything I can do to save my ladies, or do I have hold a funeral and start all over again?
That makes me think drainage/aeration is a problem. (Disclaimer: I have never grown cannabis; my input here comes from many houseplants). I tend to use perlite to improve drainage - I think I use 1:1 ratio of cococoir and perlite as a baseline, but I'm not 100% sure on that
Yup. I should have added some perlite, but it's too late for now.
