Why’s my seedling like green and purple?

I found a fresh bag seed from either Dolato or Biscotti... I forget... anyway I germinated it and then popped it in paper cup of some organic soil mixed with compost and peat moss. I placed it on my windowsill because I plan on throwing it in a greenhouse. After a few days it noticed it was stretching a bit high, so I decided to transplant it into a deeper pot and buried a lot of the stem. I decided to throw it under 2x 40w and the stretching seemed to stop, but I noticed the seedling is looking light green and the veins in the leaves look a bit purple, along with what looks like some purple coming in with the new node. I hadn’t checked the ph of the bottle of distilled water I was giving it, but I just checked yesterday before I watered and realized it was really high like 8.5 alkaline. So I adjusted down to like a 6.0. Does anyone have an idea or reason to what’s going on here?

Its totally normal, all is well it is healthy, the very slight purple/redish tinges in seedlings are a sign of health, often caused by the ultraviolet light UV radiation from the CFL bulbs, just give it lots of light and dont go changing the PH or anything radical like that, you cant over ride the natural buffers in the soil anyway.. normal tap water is about 8.5 and it totally fine as the soil will adjust it down accordingly.
Just let it grow, dont water too often and more light the better. Too many people kill their seedlings with kindness trying to fix something which isnt a issue. Looks good. you will need a more powerful light in the future, ideally 100 watts actual drawl per foot of space if you want to flower dense buds, you can get away with 75 watts but 100 watts per foot or higher is better.. just re-read your post and you plan to put it in a greenhouse to flower so these lights should be enough to get it semi root bound before re potting it into a slightly larger pot and putting it in the green house.

ok right on, I’ll just let it rock. Going to let it go a few days without watering. This was honestly just bag seed im playing with.. it’s going in a green house eventually alongside some autoflowers. I also plan on doing auto runs indoors too in a spare closet. Got a 2x2x5 tent, spider SF1000 LED, ac infinity inline.. will prob run in a mix of FF happy frog and perlite. Lightly feed with FF trio when needed. I’m just trying to figure out how I’m going to control a temp in such a small tent. My house will be cooled with AC in the coming months, and I’m not sure about the heat output from this LED light . I’m hoping it lets out some warmth though so my tents not too cold.

Here’s an update two days later -and I just realized probably why I’m having some growth stunt issues.. I used straight top soil without even mixing perlite in.. so my roots are probably struggling pushing through the heavy heavy top soil. I jsut put her into dark period,but when I wake her up I’m going to transplant into some FFOG with perlite mixed in
