Top tips: when you are using advanced coco nutrients, make sure that you soak your coco media before using it. Ideally, you should apply a ¾ or full strength feed until you start to see any run off. If you do this, your plants will have plenty of nutrients to feed on.
When using soil nutrients, always bear in mind that your soil should be 25% water. Plants thrive in soil that contains the right amount of fertiliser and water, but it is possible to drown your plants by adding too much. If your soil looks like it comprises of more than 25% water, try to drain it off as soon as possible.
