First timer, is there anything wrong with my thc bomb

I have 1 feminized thc bomb under 4 26 watt 6500 k and 2 23 watt 2500 k in Shultz premium potting soil plus 0.08 0.15 0.08 it's in a medium sized pot and the temps usually 26 in the box. I was just wondering if there Is anything wrong with my baby because the stem underneath some of the older leaves are purple and there are deep ridged veins on the new leaves growing, I water her(hopefully it don't hermit) every other day or when the top inch of the soil is dry, I ph I water and I use nutrafin ph up and down to adjust my water, water ph is 7 and is adjusted to 6.5. Any Help will be much appreciated. Also she is 2 weeks old tomorrow from when I got the seed and also only had 1 cotyledon because I was impatient and tried to take the shell off but instead ripped one cotyledon but she is a surviver

Looks good so far.

Thanks for the quick response

Sorry for the photos 1st time posting

You wont need any nutes till the cotyledon turns yellow then feed light to start with.

Home Depot down the street sells bat guano that should be good enough, I will have to do more reading in my Jorge Cervantes book about feeding because I don't know much about tea's

Here are some more photos.

I do not know why the photos keep rotating and for some reason I can't adjust them

She looks fine hun!
Some strains are supposed to have purple stems! And the deep ridges just mean she has thick leaves-- a good thing...!

Some of the leaves edges are rounding and curling down
