Have you had a look at the greenleaf Nutes? Its just one product during most of the grow every third water and then one additional one during flower at a fraction of the cost. There is a section on the site for itCheers mate, I've been thinking about how I can simplifily things.. I like the freedom of trying different sizes etc but might try a 4 pot auto pot system with sohum living soil and just add a bit of pk during flower... I'm not enjoying mixing loads of different nutes for all the different stages going on so the sohum sounds like a simpler option to transition to.

Going to try it on the grow after my next one once my currecnt nute stock is finished.
