lets say after 10 or even 30 days into veg, i want to check the soil's nutes (n,p,k ratios)..is there a tool for this? or is this something i learn through experience? from adding and observing??-please help
so the results of my ph test show if my nutes are ok in ratio? ----- i thought pH was something totally separate from nutes and what not..please can you explain further ?
