As the title suggests i have some of this which i found on a shelf,I'm wondering could i use this for my plants.The NPK is 10-30-30 is this too much K or should i stick to my tomato fertilizer anybody know the answer
I have been flowering nearly 2 weeks now I have seen articles suggest using a fertilizer with a NPK as high as 5-50-17 and i know it needs less N and more or the other 2 so I'm unsure
