It's my first Grow, going into week 3 should I go above 0.5ltr per pot?
I want to try lst, I only have pipe cleaners and I don't think they are quite big enough for me to try lst yet should I wait a couple more days or just go for it?
Wait few days for LST. Need to get some height before tying her down.
Watering shouldn't need more than .5 liter right now but when she gets 1-2 ft tall will want to increase it.
You'll have to wait a few days at least, there's nothing to train there. You could pull the light up a bit. That would encourage her to stretch and give you more to work with. Personally, I would just wait. You might not be able to do LST on it until the big stretch and that's fine!
