Burned or finishing early?
So I'm very torn about what's going on with my Jack 47 Auto. There's part of me that feels I may have burned her, and another part that thinks she's just finishing early. I have details in the diary. Any insight about what I did "wrong" would be great!

What's going on with my clones? Do not have much information to add. VPD is not terribly off, DLI around 25.
What's going on with these clones? Not sure what it could be. They could possibly be rootbound. They should have been transplanted a few weeks ago but I did not have the space.

Is 8 oz of water about right for 3 weeks old plants? Also thinking about LST, is it a good time to start that now? Also is buying nutrients worth it when it comes to harvest? Or is it more dependents on the power of the light ? Thank you for any advice 💯🙏🏼

The leaves are still curling downwards and inwards. This usually happens once the leaves become older. Although I've searched for the cause of the problem, I still don't understand what's wrong.

I already posted it, but it's better to see here and it continues to spread
This appeared after a strong storm, but it doesn't stop spreading..two guys told me it's from the wind, as I assumed, but with the fact that it's spreading further, I'm worried

Blätter welk verdreht
Die Blätter wirken welk bzw. verdreht. Sie sind heute den ersten Tag im 12/12 Modus mit anderem Licht. Was könnte es sein? Zu wenig Wasser Zuviel Dünger kann ich ausschließen sie bekommen noch fast die gleiche Menge Wachstum wie zuvor. Und davon auch weniger als gefordert

It looks like my clone is suffering overwatering. Can anyone confirm? Leaves going curl-down and neon-y. The new growth looks better but I’m wondering if since it’s a clone I should prune some of the yellowing. Any other advice/fixes welcome.

Starts to look a bit droopy after changing CFL to LED (Recovery ideas?)
When i used 72W CFL, it grew very well but it started to be a bit droopy after i changed to my 1200W LED. Light stress? Photoinhibition? Need some inputs on this. Nonetheless, i have changed the lights back to the CFL. How can i recover from this?
