first time wish me luck

hello iam currently doing my first little grow with 3 autos in a 50x90x5.5 ft tall space, in 3 gallon fabric pots,using bio bizz lightmix,under a kingbrite qb288 lm301b 240w full spectrum led,will be using mega crop nutrients at around 2-3 weeks, the temp sits around 22-25 degrees during the day at 75 humidity and about 18-22 at night with 50-60 humidity, iam also using still water brought from shop has a base ph of 7,3 and ppm of 90 i have lowerd the ph to about 6.2 and waterd 2 times with maybe a litre of water just wet the soil and have sprayed with water ever so often to raise humidity they are currently only 3 days old 1 of them with rapid growth (did have little longer in germination) and had a bigger tail then the others once planted. 1 of the seeds decided to grow upside down with tap root sticking out of the soil so i had to do some surgery if you can call it that ahaha all looks ok to me as a newbie I THINK just want to confrim my light is dimmed down to the lowest setting (not sure on the wattage) and sitting 21 inches away i will slowly brighten the light every other day once i see them ALL pop out a little above the soil my seedling thats has grown the most hasn't quite grown leaves yet looks a little weird to me (as shown below) or its just me maybe or is it just sooo young and me being a little impatient thanks for any feedback and will keep updated

yes i started nutrients on week3 i only water about 500ml-1 litre each feed iam at about 650 ppm,i only water/feed when soil is dry i like to feed in the morning after lights have been on for about 30 mins. and someone who has grown fastbuds blackberry before gave me advice to feed it when soil is really dry it seems to prefer that watering method the 1 time i watered when soil wasn't quite as dry i had a fan leaf show major over watering problem. i would suggest to anyone who reads this to run fastbuds blackberry it is rapid and getting bigger by the day iam 100% running it again

Fastbuds is consistently good for me. Indoors try a photoperiod American genetic once you find your timer and you'll see what potent top shelf snow ridden dense weed is.
