for a new guy its great that youll crop a tall plant, lanky or not; most people will overnute or over water or some shit but you fairly dialed in with a good simple rotation. next time top your plant, and train it out. theres a ton of good training guides on this site but if you get 8 nice chutes and tie down the 4 bigger ones to holes drilled in the bucket, youll end up with a nicely spread nug shrub as opposed to ur lankster. whats more, youll then be able to focus in your meager light at about 8" away and have about 2sqf of solid growth. you could also consider some simple soil amends like azomite, greensand, dolomite lime, worm castings etc.- all very easy and at given dosage will be worth the low cost
regardless enjoy your head stash until next time
