Critical Purple Auto FLower

At start of week six I scoured the plant with my jewelers loupe and did see two tiny pistils, so it's thinking about going into pre-flower now :-) I'm glad it's still essentially in veg, as the LST is ongoing and I'm tryin to space out the colas as much as possible and bring them closer to the rim of the planter.I have defoliated ever so lightly if a fan leaf blocked light from a bud site but with the LST I'm able to keep the bud sited fairly separate and distinct. Day 36 I fed 1 liter of overnight bubbled earthworm/compost tea-straight not diluted. I have done a little nutes with Fox Farms "Grow Big" diluted about half strength. I also add 2tsp/gallon of my own homemade Cal-Mag every watering. That I made by crushing eggshells and covering with vinegar. It bubbles and releases the calcium into an uptake ready form and the basic quality of the calcium in the eggshells cancel out the acidity of the vinegar. I add Epsom salts for the magnesium: 1-1/2 tsp. eggshell vinegar solution and 1/2tsp. Epsom salts to One gallon water. Got this recipe from Youtube and believe it is effective, plus it's virtually free and organic. SO far there are no visible deficiencies or leaf tip burn so I'm happy for that! My soil was a good mix of soil, compost cow manure, my compost, crushed powdered eggshells, dried powdered seaweed, perlite (lots) and some peat moss.
