I currently have my hps at 30cm.
Can I pull it it closet or is that fine? Temps are 27 with it on. I guess at leaf level it May be 29.

Looks like a phosphorus deficiency to me.
As to the purple, it's only a symptom if it doesn't disappear as the leaf grows. I have had a couple plants that had a red hue to the new growth. As the leaf got bigger it lost the red, and the leaves were perfectly healthy.
The temps may need a bit of a boost, but cannabis can grow fairly well at a lower temperature than some people think. Especially if it has been in those conditions since germination.
That’s actually one thing I tested. If a plant germinates in colder conditions it’s more hardy.

So last summer germinated a couple of autos outside and was 25c during the day and 7-8c at night. Took them 5 days to break the soil.

They did show some purpling but outgrew it by 10 days and grew into wonderful little green healthy plants.

Cooler temps can cause problems with uptake of phosphorous, and so can nute imbalances.
Damaged leaves will never recover, so watch the new growth.
You might want to up pot, 1L is pretty small, and they've been in there 3 weeks.

Since I put the hps Temps are fine. 27-28 lights on and 18-20 off.
OK. I am going to transplant it soon.
U mean they wont even grow more? I was thinking of vegging the plants for two months and now they are 25 days Old. Does that mean that all damaged leaves Will stop growing and Im left with untouched New growth? Fuck :/ that makes my plants really small for 25 days :/

I agree with Jim on the transplant and P deficiency / lockout.

Imvho, i'd add a little gypsum or dolo lime to your soil at transplant. A little won't hurt and tbh it wouldn't surprise me if calcium deficiency is the underlying cause.
If you feel a little frisky, even a little bone meal also, it'll break down overtime. As well as calcium, it contains phosphorus too.

Honestly, if your water is close enough to neutral, I wouldn't personally adjust it at all.
Don't worry about nutrient for a while either, seems there's plenty already imo and there'll be fresh soil as well.

Should all be back to normal after a transplant.

Good luck.

No. The plants will recover, the damaged leaves won't. You should still be good to veg away. They will also have time to recover from the stress they've been under. You still have the potential for a great grow here.

Its easier growing in optimum temperatures @Synch22 so get your temperatures up, close the window lol
I've been growing in cold room temperatures for years.
Biobizz or multipurpose compost and perlite. And all leds.... stop laughing now.
Heatmats are the answer. Getting the soil temperatures up is the main thing when attempting to grow in the cold, in my opinion.
It would be around 43°F in my attic now and I've 4 plants in 10 litre pots plus 2 small seedlings on a heatmat and they're looking good. I also water with tepid, rather than cold water.
Tent is at ~71°F lights on, drops to 53°F lights out.
Hut is at ~ 78°F lights on, 57°F lights out.
Purpling on plants could be strain related.
Glad to see another "Cold Temp Grower" @onegreenthumb ;)
this is spot on.
I also use the full BB nutes ecxept Heaven.
I also think that purpling is more related to generative plant material, and occurs at the end of flowering. At that time a plant will basically discard most leaves and recycle them, resulting in all sort of discolored leaves. Donno, I find it somewhat confusing that the term "purpling" is used for two entire different things at different stages of a plants development.

I Just watered with ph some where around 6.5
Actually BioBizz states that you should use hard warm water with its pH optimally @ 7.3. If you are going to grow big plants and want your plants having lots access to nutes you can influence the speed of the breakdown with temperature.

Οκ guys thnx so much.
One question. Can I transplant them with the same Light mix Soil? I dont have money right now for another soil and thats why. Also how to place bone meal or dolomite lime in transplant? In the Base of transplant ING? And how much? Thank u

Some photos of my Girls.
Im really trying to do my Best and I hope for the better. I can see some growth, maybe not so big for 25 days plant But generally they look healthy and really better than 7 days ago when I made this thread. The Girls behind drop their leaves in random times, mostly when lights go off and then they are back up again. I increased the Light distance cause Temps at leaf level were a bit high and in two days im gonna transplant them. Lets see.
