Day 36 update:
Last week I was too late with changing the water res so had a nute deficiency, changed the res and now she is doing better again :D
Still at least 35 days left before flipping to flower.
@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.
