Mephisto Creme de Ia chem

Hello all I am just beginning things here with my first Mephisto Genetics grow. I am very excited to have found this app. hopefully it stays around and improves. So, I will be growing Creme de la chem. I will be using a 300W COB LED as well as a 250W powersun HPS for the grow. Just the 300W COB LED for vegging and Both LED and HPS for flowering. I have a pair of 44 watt or 88 total watts blue spectrum LED lights from phillips brand for seedlings which, right now are being utilised closest to the sprouting seedling to keep the area warm until it pops a few centimetres above ground and I can start using the veg light. I am keeping the area moist and preparing for the Creme de la Chem to pop hopefully by tomorrow night. The seed took about 12 hours to crack on a moist toilet paper beside my hard drive. I will be using my own custom soil mixture and heres a backround on the soil im using. most of the soil was made last summer. I grew tomatoes and built the soil with lowes red bag triplemix and a giant bag of organic certified peatmoss/humus mixture. there was enough soil to top dress a backyard 50 by 70 ft big, anyway with what I used in for the tomatoes, I mixed a bag of gaia green power bloom in it and grew a LOT of tomatoes summer 2018. the one thing I did not have was perlite or proper drainage that summer. I tilled everything in the fall 2018 before legalisation in canada, filled two of my best fabric containers and brought them downstairs to further top dress them with whatever I listed above because I thought I was going to grow as soon as it became legal. well it just sat there watered a few times and the great white created a huge thick layer of all those dressings into a big mycelium block kind of thing.and I guess it dried out completely and maybe composted a bit or didnt. I'm not sure but anyways I retilled it again and filled four 7 gallon fabric pots to exactly 50% full, then I added a full top dressing of a local grow shops house brand mycelium powder (great white by plant success equivilant) (I use the great white for transplanting and seedlings and general feeding) then I filled them all to the top with perlite and mixed. it is nice and fluffy and airy now.. that is the backround on the soil. I will be feeding it with everything I've already used except the gaia green powerbloom. hopefully people can comment and tell me what they think/watch my grow with me if anything goes wrong you all can help. Thanks for taking the time to read if you did.
