This is why I love this place. It helps me figure out what I may be doing wrong. So I have
2x 16l fabric pots, filled about 90% to the top with soil
I am only watering 2.5l per pot with Bio Grow
My white widow seems to do OK, but the Haze, after the initial watering she perks up, but after a couple of days she looks sad again and looks like she's over watered or underwatered. But the pot is still heavy and soil is moist.
I do have run off, no way near 0.5l, so on my next watering I'm going to water them about 4 to 5l in each pot and give them a thorough watering.
See, I used the notion that if I begin to get a little run off, like about 50-100ml, I'm good as the soil must be properly watered to have water come through the bottom. But now I know that it still may not cover each corner of the soil in the pot as it may have found a quick route down to the bottom.
This is my first soil grow, so far so good, only with the haze issue! I am a still a bit concerned as I read that it may be a pot issue as I have been veggin for 10 weeks and it may have overgrown the pot, lets hope its just the watering issue as generally they are healthy.
Thank you for your response @flip
