Here's the thing to remember with nutes in any setup...variety. Thats why you see so many of the same manufacturers with different sources of the same nutes. Nitrogen for instance, why feed a plant only one source of nitrogen. Like diamonds are different due to chemical makeup so are your nutes bloodmeal may display one variation of nitrogen while while planting beans as a companion plant to your weed will do another variation (yes this works quite well). The same as you wouldn't be that healthy just following food guide pyramid with one type of food from each food group, so would your plants. Survive yes, thrive no. Coco, peat, clay, straight compost... That is all well and good and they need different methods for each. So to answer your question, for any media look at it like this, how much nutrient value does my soil have? In your case slim to none so start low and go slow using a variety and dilute it gradually making it stronger. Your plant will let you know if its too much or too little but if you start low and go slow your a lot less likely to burn your plants than going by a predesignated pattern. Each plant is different, my sister eats kale, I fuckin hate it same with your plants. Ive had clones of plants that like different nutes so there's not a one way suits all. Buy several types and dilute them and swap them out back and forth. IF your plant doesn't like it shell bitch like a crazy girlfriend until you get the hint.
