I think I have proved that even though I washed it I reused my coco one time to many no matter what I tried it just stopped any buffering/stabilizing of the root zone . the ec was 1250 ,Ph 6.5 going in and a runoff of ec 1050 and ph 6 ,should be healthy plants right nope out of the 4 sour patch kiss 2 gave up the ghost the other 2 just stopped growing and the 4 blackberry dream never recovered from that last lockout about week 4 so they are very small ,my plans are to cut and hang the spk and use it to make oil and harvest the bbds im not expecting to get more than an ounce or two from each plant , I will take pics when I go down this Morning sad but hey the young ones are doing great and need the space ,
