Attempt at Water Only BuildASoil

SO! I'm starting this diary at week 3. I decided to document this for myself as much as anything, since I've been growing for about a year and I wanted to upgrade my methodology. I've been reading non stop for months and this grow is me investing a little and doing everything as close to (what I know as) perfect as I can. Criticism is still more than welcome, if not specifically appreciated. Seedling - I just have one going, as it was my last one and the new batch got delayed in shipping. Right now the plant is in a 2 gallon pot full of Ocean Forest, topped at 4 nodes, and LST with some small metal hooks to spread it out in preparation for Scrogging. I want to let the final pots soil sit while moist for a week as is recommended. NOTE: I actually germinated 2 seeds for this grow. Both took FOREVER to pop up, and one made it above the soil and died for seemingly no reason. The surviving seed is way shorter than normal. Not sure what happened but its otherwise very healthy. Soil - My soil is made by following the recipe from BuildASoil. 1 part Sphagnum moss, 1/3 part compost (mine is Compost/Manure from a local place) and 1 part perlite. Next is 2 cups/gallon of Nutrients from the BuildASoil Pre-Mixed Kit, and 4 cups per/gallon of Minerals from the same kit. I'm also using the Clover mix cover crops. Pot - I guess I could have maximized further by using an expensive Smart Pot, but i opted to save my hard earned cash and use a 27 gallon storage tote. LOTS of holes, garden cloth, ~2in layer of rocks, and another layer of garden cloth. This might be overkill but it wont hurt it. The plan is that since I only have one plant in a 27 gallon container, ill let it veg for way longer, I'll basically play it by ear, but I'm considering let it go up to 2 months total, and hopefully not need to add nutrients all the way through to harvest. If I need, I can top dress or make a tea to keep it healthy. Watering - for a few more weeks it will be by hand, but I'm working on setting up an automated drip/sprinkler with some nifty mini-sprinkler heads I found on Amazon, a branch off my water hose, sprinker timer, and an an RO filter! Wish me luck!
