Auto Massassin First Hydro Grow

I'm trying to be as accurate as possible with measurements and dilutions as it's a hydroponic grow, I have done a lot of research about growing both Autos and Photo types and think its time to put all I've learn into practise. I'll also try and get a photo at least every 2-3 days. The Auto Massassin seed took a couple days to sprout and came out on the 13th October, I transplanted it a couple days after. During the Week 1 the roots didn't touch the water in the pot, I think its because I transplanted a little late and the main tap root ended up dying/drying out? From sprouting I sprayed the seedling 2-3 times a day for the first week to keep the humidity above 90% I monitored the PH of the water even though the roots hadn't reached the water and maintained it at around 5.8-6PH I've used all the nutrients more than 50% below the recommended usage to see how the plant reacts as I read some autos prefer lower nutrient levels. Was unsure how to say how much Great White to say I used, just a tiny sprinkle or 1/10th scoop. I lowered the PH with about 6 drops of PH down and added 3ml of the Silver Bullet Roots to the 16 litre pot (which was recommend to stop root rot) So I live in a hard water area so use 1 drop/litre of Neutralise by Ecothrive to neutralise chlorine and chloramine in the water. I can't measure PPM or EC because I don't own a test/pen. I don't own a Par/lux meter so am guessing the light distance and only have the veg switch on My LED light is rated at 1200watts but when tested with my plug tester it measure at approx 45watts in Veg and 70watts in Bloom, both switches on use about 115 TrueWatts. (I think that's how it works)
