I could have early stages of root rot but not sure. This is my first try at Hydroponics. I was told I may be watering WAY too much for my young plants (4 weeks old.)
I started
seeds in 1.5" Rockwool cubes and after two weeks moved the seedlings into my newly built
hydroponic system (Lettuce & Basil in one system, Broccoli & Cabbage in another). This is my first grow.
The (2) flood tables are filled with Sun Leaves Rocks. The small plants sit in rockwool-in 2" net cups-in the medium which I was flooding 4 times a day under 12/12 T5 HO
lights. I keep the
nutrients at the following:
Lettuce/Herb system @ 1.0 EC
Broc./Cabbage @ 1.4 EC
Reservoir temps have been around 70 degrees F.
Well my Broccoli which is 4" tall with about 6-8 leaves, have started to bend over half way up the stem. The stem at the base of the medium looks a little thinner and looks a little light purplish brown. Is this root rot? 3 out of 10 of these young plants display this. Perhaps I can catch it while it's early?
