Yep they are nearly done.
Ill know better for next time

Ive also got two plants in airpots that I planted at the same time. The airpot plants are slightly further along ( about a week), always been smellier than the Hempys, but smaller (even with the Hempys small pot) and much harder to feed/water.

For a first timer its hard to get wrong. You can't over-water or underwater. Never looked at pH or EC.
