Fast Buds banana purple punch

I messed up a little and got mixed up with the medium not knowing weather this was coco or soil so started feeding synthetic nutes at 5.8 ph for what I think is coco. The growth isn't where it should be so I decided to go back to feeding organic nutes at 6.5 , this didn't help . What a cock up Im now feeding at 5.9 ph with these nutes and will water till there's run off next time. Hopefully I can bring her back to better health. I think im going back to soil growing suits me better and the taste is also better in my opinion
