Never grow at 24/0............all cannabis plants NEED "sleep" for a correctly functioning metabolism.
18/6 is optimal.
A plant with and incorrectly functioning metabolism will never grow to its best potential.
Certain metabolic processes can only occur during the dark period. Without this dark period, these processes can not happen.
This is how photosynthesis works.............activity followed by rest and recovery.
In soil, I use a schedule of plain water/plain water/feed/plain water/plain water/feed...........have done so for over 30 years and it works for me.
