The difference I saw when using RAW was mainly top dressing one day then two days later the plants just look visibly better and the roots are bursting through the airpots nice and white.
I just use straight 60/40 but am switching back to Canna Pro straight coco no amendments.
I have some Jack Herer on the Athena and have cut back to 1.5 ec but they are not happy (I know Jack's can be a bit finicky). They were showing iron deficiency which I have never had but when I checked the run off PH it was over 7 with only 5.8 - 6 ph going in so Iron deficiency makes sense I thought it was mag at first but it is affecting new growth. Flushed them today with gallons of PH water and the PH just won't go down. They are only in 2 litre pots at the minute and 5.5 ph water going in gallons of it but still run off is 6.2, I can't understand it, gave up in the end and fed at 5.6.
