@inspireme Ya know.... this is Green Crack Auto by FastBuds.
The company site and many blogs have described this strain as a hungry one, particularly during flower (very exciting). This is why I asked the question. If I was to bump up the ec to 600 over the next 24 hours, as you suggest, how long does it take to see the results, a couple days? (This is my first grow if you don't count the failed launches. lol) Thanks.
