Thanks I'm a new grower I'm using 10liter posts and watering 2liters of feed/water witch is from a 24liter reservoir witch I add 20ml coco a and 20ml of coco b every 2 days is this too much or two less feed?
It's brand new don't think needs calibration will get some solution to test the kit and yes it's suppost to stay moist witch it dose I never let it fully dry out
Lights was 12 inch away I've moved them to 60cm away to try introducing a little stretch I've been giving 20ml A and 20ml B in 24 gallon water butt pH is 6.2. ec around 1766 as only got pH and ec tester kit yesterday
