That Painkiller is over-ferted and has been all along. The first pic you have of her hurting with burned leaf edge and length-wise curling, (canoeing/tacoing) is nute burn. Sativas don't handle hot soils as well as more indica leaning strains. You should give her a 1 volume flush and see if she perks up. In other words pour the same amount of water as the volume of the pot she's in thru slowly to tone down but not remove all the nutes in there.
She doesn't look like she's burning now but if she's on the edge it will hold back her growth. None of those plants really needed added nutes with soil like you're using until quite a bit bigger. Too much too early will stunt growth rather than promote it. New growth should look yellow at first until the light greens it up. Just means they are rapidly growing.
HPS would be great for flowering but if you used an HID light at this stage you'd want an MH grow bulb.
The others are looking real nice.

This is exactly what I needed: "Sativas don't handle hot soils as well as more indica leaning strains."
Fortunately last week I when it was in that 8" pot I watered it twice (5 days apart) until water ran out and it has started to come around nicely, taller with a lot of new growth. The only additive was the Cal-Mag so between the Mag and flushing, one or both have helped. Now I'll need to watch closely because I moved it (PK-XL) to it's 5 gallon pot a couple days ago so there is fresh soil again. The initial watering was a thorough soaking so I'm not sure if I should flush it again or wait to see if it's big enough now to handle the extra neuts in the fresh pot. Thanks for the heads up on the soil OldMedUser. I have several Sativa dominant strains on the way for my next grow as I will be focusing more on the higher CBD strains. What soil would you recommend? I mentioned it earlier on but I used 1/3 each Fox Farms Ocean Forrest, Perlite and PromixBX.
This PainKiller XL sprouted 36 days ago.
Thanks for ALL of the reply's. As far as lighting goes, I need to make due with what I have for now.
