That will get you to next crop you greedy gums. ;-)
I hope its been on full power for most the grow in flower, tbh id leave it on full whack right till chop, remember its last few weeks they really start popping packing on more weight.
Think this is a load of shit and more like bro science myself.
I chop when ready usually after water has been cut off for 24 to 48 hours before hand.
