I moved onto Plant magic coco nutes and supplements mid grow after some problems with canna (canna are very good but not for me). I havent looked back since. My grow is a different experience, the ladies are now flying and exceeding expectations. Cant say enough good things about it, I think 'essence' is an excellent product in particular and I am a pretty sure the key difference with these products is the positive effects on roots. I have very hard UK water. I had an initial concern with the amount of PH down needed at the beginning cause my starting PH before nutes is very high. However, now the ladies are eating well and the amount of nutes added has increased, I need very little PH down .
I have no connections with Plant magic at all but wanted to share that I am totally chuffed with the difference they have made over canna in my water (no reflection on canna, they produce awesome grows but I am a beginner) - the icing on the cake for me is that is a UK company....something I like to support against the dominant Dutch cartels
