dude you should go and have a good soil if you want experience something,ı did the same thing as you..get the soil without ferts from my garden..and could change only the half of it at late veg.this shit is too heavy and hard.plant cant even absorbing the nutes and water.u have to dig every 3-4 days for oxygen and absorbing.its also bad for drainage..ı had to open lots of holes after realizing it.and it really slows the growth.not talking about the plant problems which are probably about it.also buy the cheapest ferts containing n-p-k with another containing seconder elements cal-mag,zinc,etc.if you want an oganic grow u need a soil mixed with ferts like bat shit,worm shit,fish emulsion or some other shits.
