AsNoriuanswered grow question 3y ago for weed soil, use 50% perlite and 10% worm humus, you don't want to burn young roots, humus aka worm castings is very potent
i was starting big pot with 200 ml, 3x50 ml every 5-10 min , to centre spot were seed will be, put seed, cover her gently, water last 50 ml.
if your grow temps are not too high and humidity is above 60 - plant will need 100-150 ml every 4-5 days for first two weeks, but i am spraying them too for bigger moist.
plant grows - you increase amounts
my biggest girls were drinking 5-7 liters every 3-5 days
with small pot it will be 2-3 liters every 3-5 days when she will reach her size max in 10 liter pot, doubt she would consume more
so as plant grows you will water more
watering good ph and on time is ESSENTIAL in weed growing, forget all techniques and feed even, your main target are those two !!!!
water when pot is light and good ph, you already at 50g mark with 10 liter pot, without food even, if soil was good at start
