Half strength is 550ppm? So that means they'd have you giving your starts 2.4ec
How are you measuring out?
I have 3' tall plants in full bloom. I'm backing off at 1.2ec (600ppm) because its too strong
It says 1/4 tsp per gallon which is full strength. .25 divided by 2 (half) is 0.125
0.125 tsp to ml is 0.6 ml
I added .6ml of Foliage pro and .6ml of Protekt and 1.5ml of calmag (botanicare). I measured the PPM of the tap water and it was 550ppm
