It’s my first time growing anything and I decided to try growing Tiny Tim tomatoes in an Idoo 10 pod hydroponics system. I have been adding the nutrients that came with the system and have been deep cleaning the system every two weeks and adding water in between to maintain 4.5l. I’ve been adding 13ml of 3% hydrogen peroxide to the water too every 5 days. Originally there were 10 plants in this system but I removed two weaker ones as they were dying and very small.
I noticed a few weeks ago the lower leaves have started to die and fall off and this has been slowly spreading upwards. The leaves appear to have some brownish circular looking things on it and I’m not sure if this is a fungus that is spreading or what I should do? I’m a complete newbie to growing anything so any help is appreciated!
