Blue Dreamin' in the South

I setup my tent and have been letting it get climatized to the temp/humidity that I'm looking for when in flower. This is my first grow, and I'm attempting to do (4) total plants. All (4) seeds were placed in water in a shot-glass to start. (2) seeds stayed in the water until I saw their radicles. (1) seed "Ariana" went straight into my soil mixture after 4+ hours in the shot-glass. (1) seed "Calista" went straight into a Root Riot plug after 4+ hours in the shot-glass. (1) seed "Demi" soaked in the shot-glass until the racile popped out a few mm's and was then placed directly into a Root Riot plug. (1) seed "Bernice" soaked in the shot-glass until the racile popped out a few mm's and was then placed directly into my soil mixture. I'm using PREMIER HORTICULTURE 713445 PRO-Mix HP Biofungicide + Mycorrhizae as medium and mixed 1/2 of a 15gal bag of earthworm castings to a 2.8cu ft bag of PRO-Mix. I started to lightly feed on 02/10/2021. My nute mix is currently General Hydroponics RapidStart and Fox Farms Big Bloom. I mixed 2.5 gals of nute mix at half-strength of recommended EC/PPM, which reads in my mix at 0.7 EC/470 PPM *700 scale* and have the PH set at 6.0. I'm going to use a small dropper to place a few ml of nute mix around 1/2" from the base of each seedling. I'll likely continue this regimen for a few days and monitor the progress/changes. So I had (x2) seeds that failed on me: (#1) didn't ever "pop" in water and no germination occurred and the other (#2) that was directly sewn into soil as a seed.... I ended up popping (x2) more seeds on 02/11/21 so that I could keep my grow as (4) plants. These 2 additional seeds will be a few days behind the others but I'm going to be doing some LST training on a plant or two (smallest ones) and I'll find out which those are in the coming weeks.
