First grower need tips

Earth worm casting is enough for plant to survive on. More stuff will get you bigger plant and bigger buds at risk of killing your plants by overdosing. For first grow, I would take it slow and add one or two item each round. Later on there might be problems. And I think it is safe enough to have some of these items ready. Bugs and mold control. I use microbes. More expensive and less effective. I just don't want chemical stuff in my body. Beauvaria Bassiana, Metharizium both work well for me to control spider mites, gnats, and aphids. If you don't have humidity control - you should get Trichoderma. This is basic microbe to control bud rots on stickier buds. For fertilizer, Bone meal should be added after a month so your plant can store up calcium. It is "immobile" fertilizer. This means that it is difficult to add on later. Bone meals also gives phosphate that EWC may not provide full amount. Use only a little. During flowering, I add sea weed to help promote flower.
