More details since the feedback I'm getting seems to pointing towards user error.
my ph stays from 5.8-6.2
my reservoir temp is 69-72 degrees
outdoor temp is in the low to mid eighties
my current flood cycle is every two hours, I have also tried once every six hours.
my e.c. is 1.0-1.5, I have tried higher amounts but the plants didn't seem to feed more.
I have been mixing my
nutrients (chem-gro 4-18-38, calcium nitrate, magnesium sulfate) to the manufacturers instructions with reverse osmosis water.
The only thing I haven't done is add calcium chloride as directed by manufacturer since my base water has under 50 ppm calcium.
Could it be a calcium deficiency?
