    Does look like PH lookout. Is this new coco or reusing from prior grow?

    Well you must wash your coco if it isnt pre washed.

    Run tap water gently through the pot.. until ec is 0.7 as your tap then add 0.3 ec of your AB fertilizer and id work with a reverse osmosis filter if my water were so hard

    What brand of coco are you using? If it's general hydroponics you don't need to wash it. I don't think you need to wash canna coco either. Cheaper brands will often have salts from the ocean as they just sit out on tide lands, those you have to wash all the salts out.

    What are you feeding? are you feeding with every water? Are you getting good run off every time you feed? Your plants simply look hungry, but you could have a problem with your pH meter.

    Hiya chaps I'm using ecothrive Coco so I think it's prewashed. First run not reused. I'm using dutchpro for Coco at half strength as they are only like 12 days , I think half strength anyway chart says minimum 250ml per 100L so I'm giving 12.5ml.of A and 12.5ml of B to 10L. Does that equal half strength or full strength? Only occured to me earlier that I didn't know if the feed chart meant 250ml of each A and B or 250ml combined. Cheers
