3200k my personal or 5000k a mixture of both would be Ideal I don't know why you would want to only chose one though. This is all LED based I assume are you counting MH bulbs they can be very good for vegative growth just expensive to run.

From 24h to 18/6h during flowering ok (autoflower)?
Royal AK47 Autoflower: Changing from a 24h light cycle (since beginning) to 18/6h when already flowering - no problem or not recommended? The temp is a bit too high (~30*C) I think.

Distância e potência do Led
For the seedling stage: Is the LED power at 25% (mars hydro TS1000) and a distance of 60cm from the plant adequate, or can I reduce the distance for better growth during this stage??

Is this a sign of too much light?
I’m noticing the leaves grow extremely close to each other, should I be concerned at this stage, should I pull the light higher back? This is day 3 of week 2, I’m feeding it full advanced nutrients line up for veg. And drying out for a day and a half between waterings

Additional lighting in flower???
I’m planning on putting another 2 x 600wLED (blurpul colour type) alongside my current 2 x1000w led Cree cob lights. I have them spare and was hoping this will help with flower/thc production??? Is it worth putting them in or just wasting electricity. Any help appreciated 🤙✌️🎄

😂😂 The heat problem was back... well, now I had to hang the lamp 40cm higher, just put in new poles and made the tent taller. I hope it's not too bad for the ladies. But there was no other way; the temperature at the highest point of the plant was sometimes 33 degrees.
