This lady is blooming so nicely outside of the little leaf with spots this lady is doing very well. Last week I have tried the peroxide mix in my resi so I'll see if any more come up plus I'm keeping the resi around 20Β° or soπͺπΎ stay tuned.
I got some spots on the leaves of this autoflower in hydroponics also there's a little discolouration in the roots I'm not sure if that's the reason any help is appreciated.
Looked like you have some rot going on. You can treat her with some peroxide for a day, change the water, and then incorporate a compost tea without using molasses. Brewing a proper batch of compost tea and adding it after every res change will help keep the good bacteria flourishing which will kill off the bad destroying your roots. Also, make sure you have good airflow, turn that reservoir into a cold jacuzzi for your roots.
You may have to trim away some of the dead root material and as a last resort, you can transplant her into coco coir. Coco will retain a lot more oxygen in the root zone which also kills off the bad bacteria and you can use your hydro nutes. I personally have done this last step to save 2 dec plants.
