Im using jungle juice coco bloom great stuff with cocotek. Use it ,i want to say this the plants with out a slow release food love the stuff,the ones with the slow release dont like it ,thats my fault tho i mixed it in .thats the coco one it was 17 bucks i couldn't pass it up. It works very well in coco great growth just make sure there is no food in the coco.wish i could show you a pic but i use a cell easier to upload pics just no quality pictures at all. Im not a fan of advanced but it works well.one more thing im going to say dont use coco that has slow release food. cocotek rinsed well and buffered to a ph of 5.8 works extremely well.
