"Special mix contains enough nutrients for almost a complete grow cycle if you donā??t water with drain. If you water with 30% drain it contains enough nutrients for the first three to six weeks. However, donā??t wait until you have completely exhausted that supply and it starts to show on your plants. We recommend that you start with a very light feed after about 3-4 weeks to maintain the nutrients levels in the compost, but only if you use mineral nutrients and if you fertigate wit drain!"
