4x4' 4-way LST SCRoG first attempt

All seeds except for The Church sprouted. Using rapid rooters soaked in 230 ppm well water with no added nutrients. Moved into starter pots filled with straight sunshine mix #4, then put in a 2x2' tent with 100W T5 4-bulb fixture 12" above the top leafs, inside of a humidity dome. I chose 4 plants as I hope to fill out the tent with an extended veg time using 4-way LST and SCRoG. It's my first time using SCRoG or LST, I've only ever topped before in the past. The main and most important goal of this grow is to defeat lockouts, I am using this medium and nutrients based on advice given to me by a grower who has well water also. I had used bottled nutrients exclusively in the past, other than organic growing, but I have always enjoyed the explosive growth you get from hydroponics and soil-less mediums. Anyway, I am always looking to improve my grow and find the cheapest way to do it with the least amount of problems. If everything goes as I've been told, this should replace my current medium and fertilizers.
