No. Just started a grow with it but love what I am seeing so far. I've never seen plants respond that way to a 1st feeding before. It could have been a fluke but dont think so. From my research and what experience I have with it, it dissolves better than anything that ive ever used. It dissolves better than jacks, megacrop, a lot better. Maybe its because the doses are so small. But it does dissolve like a dream. 29-61-50 npk is the highest water soluble npk available to the public. I also use their silica and humic acid. The humic is 57% which is fantastic. But I will keep folks posted as the grow continuesDid you run a full grow with the RAW nutes? Are you modifying the feeding chart at all?
