I watered my oldest baby yesterday, soil today was dry so I watered, but it's droopy

Help me out

Pot/bag is wayyyy to big for the plant and if you havent much experience you can easily overwater it which will take forever for the medium to dry. Till the top soil, help it breath and see whats going on a few inches below. Top may be dry but under can be sopping wet. Get a feel of you pots weight with a hydrated medium and when it drys.

get one of those $10 water probes from home depot it will tell you if your soil is soggy 6" down

also youre using 100X more light than you need. Assuming electricity isnt free where you live

Assuming you're not growing auto$ .

Potting up correctly ensures the roots fill out the space evenly which allows even saturation/drying of the medium when watering.

Roughly double your pot size every 10-14days allowing the final pot to be fully rooted out before flipping 12/12.
Like this....1L >3L>7L then into the final 15L.(e2a you only need a 15L pot if you are growing trees)
