To tight nodes?

Yo! Is to tight nodes even an issue? Everything looking good and green...and/but very packed. Week 4. Babies at 40cm ish

Led 2×220 meanwell samsung homemade shit at 50cm from canopy...

Should I heighten them?

Is it the closer the better with led as long as you dont get bleach?

One love guys

Tight spacing is a good thing,unless your trying to stretch them out and fill a area or something. If you got room you can raise the light and tie the plants every which way to fill the canopy.
If space is a issue keep those tight compact plants doing the same thing you are now.
