I use water the entire time with a super soil mix I've created over the years. I have no ppm/ph issues and no hassle with expensive bottled nutes, plus I recycle the soil and amend it which lasts for years. If you wanted to make a super soil next time, find yourself a starter recipe online and mess with it for some time until you get it dialed the way you like with the mixture you like. At this point you're probably getting closer to "scissor me timbers" and everyone has the way which works best for them. If you create a healthy soil composition your plants will feed on what they need in the soil. The taste is better,cleaner, and healthier than what many will smoke 9 out of 10 times. Plus, always give your plants the room they need to grow in bucket wise. For that size plant I would maybe also try a little bigger bucket. With straight water all I do is filter out the chlorine and keep the minerals. No RO. The plants act like they should,turning all the fall colors you would normally see at that time which takes out a lot of the harsh chlorophyll taste, if your mix is correct..
No, they won't be as jacked up as the plants on steroids. But you'll have the piece of mind of smoking healthy cannabis. Also, less chance of mold happening. If you mix the ratios correctly you can figure out how much to amend for how ever long and recycle your soil every year.. I've tried very expensive products and this gives me better smoke IMO. Plus it's way less maintenance and cost less.
