I have not seen any improvement since the flush so I drained about 4 liters of water and replaced it with water with no nutrients

So the nutrient solution should be at about 0.65% strength rough estimate

from the original 80% solution

I am starting to wonder if I should stick it out a few more days to see improvements or whether I should switch it to pure water for a few days and wait till they stabilize

I'll answer any other question not answered in the journal Seeds were planted 9/07/08 making the plants 34 days I think its probably due to salt build up so I did a preliminary flush since I do not own a PPM meter and never had to last grow Rating: 5
