Moved to a slightly bigger tent where I can actually fit both plants in for flowering and upgraded to more powerful LED light. Upped the nutrients to the full suggested level for vegetative cycle and started watering every day. Topped after around the 5th node in the middle of the week and defoliated a few of the old leaves that were stuck down in the shadows at the end of the week. One of the plants seems a little yellow-ish, not sure of the exact cause but hopefully the full nutrients and more frequent watering will help.
