  1. 651356A4-98AD-4D18-93ED-A3CD2A136DE2.jpeg does anyone know why my bottom leaves are yellowing/browning and cracking? The rest of the plant seems healthy
  2. Probably nitrogen deficiency, but can't be certain with those purple lights. Need a pic in natural light with flash to be 100% sure.

    I’ve also just noticed one of the bigger leaves has gone black/purple?
  4. The even paling/yellowing of the bottom leaves is usually a sign of nitrogen deficiency. The black/purple leaf looks like something else is going on there. Hard to tell with pics looking a bit dark.
