<span class="link_user">@UncleIsko</span>, I've tried it. From what I've found the tea can hold a spawning spot for mould so be careful. I personally don't use it. I've found the best supplements are the premixed fulvic acids and nitrogen mixes during veg. I then just continue from a 300ppm base feed with added calcium (because I only use rain water) in veg and slowly increase to about 900 in full flower. I give one day of plain rain water roughly every 10 days as a salt flush and found them to never be deficient.
