I think I see 2 things. One is early nitrogen overload. Two is the aluminum foil. Use white on the walls and nothing on the floor. Might add a little cal/mag if this continues, and yes, transplant to fresh pot.

But, I did not notice a problem that is specific. What is your worry? I saw your other post where you were worried after only 9 days in flower, which, by the way, the plant has started the process to flower, should see the flowers soon.
