Plants are really looking way better today after I put the hps 250watt. Leaves are no more so curly and Ive noticed also some significant growth. What do u think?

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.
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.
As I said above...

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.
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.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 :/
this is spot on.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![]()
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.I Just watered with ph some where around 6.5
I don't know anything about your soil, but I don't see why not. Is it labelled seedling mix or something?
