Overwatering?

Wonder if she is showing signs of dry pockets? By watering a specified amount and not fully saturating the pot is an easy way to have dry pockets in the medium. Dry pockets can't take nutes and can damage root system. Like everyone else said, fully saturate and then leave it until the pot feels light again and repeat. Best of luck! Happy Growing!

I’d guess that 1 liter of water after 5 days is damn well not over watering.. Fully saturate your soil until some comes out the bottom and do the same again when the pot is light. If you can’t lift it, stick your finger down in it and if it’s dry, or barely moist, water again.

Looking at your pictures and reading your diary. I can’t figure out where your at with this grow. Are they the same plants. If so you’ve changed your lighting DLI, your watering too much or not enough, you need to let it dry out a little between watering, and what kind of nutrients are you feeding. The leaves are yellowing like a N deficiency.

They don't seem too overwatered, but you can lift the pots to feel their weight and see if they feel light. I recommend that you dig about 2 cm or so with your finger, and if it's not moist at that depth, water them. You can also stick a wooden skewer in and see how far down it's wet. That's how I do it.

Stop worrying about amounts and days and water by weight. When the pot is light give it water, when it's heavy don't.
