Eco-grow/ecobloom 4 Soil?

Is it alright to use ECO-GROW during vegetative cycle and ECO-BLOOM during flowering cycle on a soil plant even though there 4 hydroponic grows?

It should be fine, but I would recommend using half strength at first since they are more prone to crystalizing out of solution then soil fertilizers. I have used the general hydroponics line of fertilizers in soil, I went to FoxFarm in the end because I got sick of flushing the soil and Foxfarm is pretty cheap for a high quality fert.

I would wait atleast untill the second week before using nute's
