Red Stems - Strain trait or K deficiency?

I've had this plant since it started off as a stunted little throw-away plant 3 weeks ago, and it's made an amazing recovery. I thought it was doing well, but I posted pics on another forum and members there were telling me it's got some problems. They suggested a K deficiency, but I was wondering if it was just a trait of the specific strain I have.

Technical notes: The environment is staying at a temp range of 68 - 80F with a relative humidity of 34% - 60% (60 during morning watering 34 at night). Lights is a 40W CFL 1" away from the tip of the leaves on 18/6 (On from 5am till 11pm). 2 80mm fans run during the photoperiod. I give it 150ml H20 every morning and leave a container of water in the corner to boost humidity and lower temp, misting after feeding to strengthen the stalk and keep the humidity high throughout the day. I visit often and talk to the plant (busting out rap beats about how big it's growing :P) to keep the CO2 up. Haven't fertilized it since after the transplant, and I noticed since then the leaves aren't spotted and the plant is doing way better. I inspect it for bugs and take them off by hand. All in all I spend lots of time checking it but more time letting it do it's own thing and it's paying off.

The fertilizer I've been using is called RapidGro 20:20:20 blend, 1 tsp mixed with 4L of water. I used 60ml of it for 3 days right after transplant because the leaves were becoming spotty. Haven't used it since then.

Side note - is this nute burn/lockup, light burn, or nute deficiency?





On another note entirely, now that it's preflowering, should I change the light schedule or anything else?

Ha weed ;)

I added 60ml of fertilized H20 (RapidGro 20:20:20) 2 days ago and theres no new red petioles or streaks on the stem. I checked an old pic of the site I found the plant, and from the looks of the discarded leaves they all had red stems too. So looks like it's a natural trait of this strain, but the nutes can't hurt too much anyways.
