I have used these nutes only once before, on a Sour Diesel grow in DWC. The nutes worked well in DWC but controlling pH swings was a bit of an issue. I'm pleased with how they have performed in coco, the plants have grown well from the start. The only problems I've had have been caused by me. They are a bit pricey, the base nutes aren't that bad but the additives can get spendy. For 1 liter of any of the additives my local shop charges $67.00, the Vitalize is worse at over $100 for a half liter. I think I could get 3-4 full grows out of a 1 liter bottle with the size of grow I have now.
