gdogfunkanswered grow question 5 years ago There are many options out there for plant food. I used to use GH Floranova Grow and Bloom, but they are kind of a generic plant food good for many different plants. Since they aren't targeting a specific plant, they include a lot of extra salts that can buildup in the soil and thus require a good flush at the end of the grow cycle. I've since switched to the Emerald Harvest brand of plant food since it's specifically designed for cannabis and contains plant-based material instead of animal-based material and is much more helpful to the plant. It also contains much less salt than the GH line and doesn't require the large volume of water to flush at the end of the cycle. I also like to supplement the flower stage with MammothP for extra fat buds! I've had good results with both approaches, but I prefer the Emerald Harvest line these days. I hope this helps!
