Look up MHP Masterblend by Tyler. 4-18-38 is the rating it carries, and you mix it with calcium nitrate and Epsom salt in the water. The calcium nitrate being seperate lets you back off the nitrogen as you later need. It is the best fertilizer I have ever used. Not only do you get huge are productive plants, you get incredible flavor. People always think my produce is organic. It has that rich developed flavor of organic. I found out about it on YouTube. This country Virgina grower that goes by MHP gardener. He only does food crops on there, but I do roses, tomatoes, peppers, orchids, and obviously cannabis with it. I think it could make damn near any plant thrive. It works equally well on hydro and soil.
