First grow improvisation RS11

You can definitely replant her into a bigger pot (like a 5-gallon one), but timing is key to minimize stress. A good rule of thumb is to check for roots peeking out from the drainage holes at the bottom of the current pot. If you don’t see any roots yet, there’s usually no need to transplant just yet. Regarding LST (Low Stress Training), you can still do it after transplanting, but give the plant a few days to adjust before applying any additional stress. As for the node spacing, dense and short internodes can be a sign of good light conditions, so it’s generally not a problem.

Don't defoliate! ALL of the plants energy to grow and thrive is made by/in the leaves. Less leaves = less energy being made = less potential growth..............it is that simple. Besides, light spectra we humans can not see will actually penetrate upper leaves and strike so called "shaded" leaves underneath, making defoilation pointless. Defoliating such a small plant would severely reduce its ability to make enough energy to grow as fast and big as possible.

Thats root-bound signs. Also if it was in a smaller pot as you said. Its intake of water would be high within a short time which can also give those tips

If nothing changed in your bahviour its probably just stress from replanting. if the earth didnt stay as a cube; roots and definetly microroots broke and the plant is stressed for few days. Good luck with it

if you use a trellis for only support, you still have time.. figure about half way up the future vertical growth is good for support. If used to help train the plant horizontally, put it on now or even before this point in future grows. Defoliation is not wise. Selectively pruning is fine. Always have a reason to remove a leaf. They do several important things for the plant - light absorption, molecule production/building, and they are the lungs. So, if you dont want to reduce the limiting factor of CO2 intake, don't blindly remove a bunch of leaves thinking it helps.... There''s a chance you delay flower due to the stress of it, too. Read "to defoliate or not..." on cocoforcannabis.com. the guides and posts in dr photons corner will help you avoid numerous urban myths/bro-science nonsense.

maybe some overlapping leaves that cause condensation / standing water would be wise. just be selective. Leaves do several important things including the 'lungs' of the plant. you should never take off so many that it'd cause a stress reaction. really shouldn't be an issue as to when you remove a limited number, as few as possible, leaves. if you think there is a risk of mold or infection, don't wait. The plant won't react adversely to a small percent of pruned leaves.

It's your first grow. Best advice is to keep it as simple as possible. Hubris of man is to think we know better than nature itself. Observe how the plant defoliates itself. In the future you use that experience to preemptively defoliate that which you know will be of little to no use come later in flower. Over explaining everything only serves to confuse. I guarantee any defoliation you do now will only lead to detriment. She looks healthy and happy and I'm impressed with your first grow well done. No need whatsoever. Most people stress their plants so much in the early days, 6-7 weeks of growth and plant has mass of a 2 week old grown with 0 stress.

Kinda the same way that a babies skin isn't the same as a 50yr old man's. It is more obvious in the morning/before lights on. The growth that happened in the dark hasn't seen light yet and hasn't started to photosynthesize yet. Nothing to worry about, it's a sign she's very happy.
