day 43:
Topped for the 2nd time this morning.
All going slow and steady --> not using enough air pumps to get full potential from the DWC system, but anyway they have another 30+ days before moving to the flower tent so don't want them too big either.
@SleeplessWalker,
Im trying without flush this time, I just removed the base nutrients and the sugar supplement and reduced the nutrients by a lot during the last 2 weeks to see how that turns out... So far on the early sample I tried it seems very smooth. Next round I will try flush 5 or 10 days.
