Guess the week of flowering

[allotment]

Before we go into that loop again, the whole flush or no flush thing has been discussed here

To flush or not to flush?

I have recently found myself talking about flushing on this and other sites. I have a friend who uses the same clone as me. We sometimes compare our product to evaluate growing techniques and so forth, also a little healthy competition, hehe. I do not flush, he is at the other extreme and does a three week flush, which I think is excessive even for flushing. In order to keep his plants healthy, just before starting to flush he has a PPM of aroudn 1600, whereas the highest I go is just over 700…

(my guess would also have been week 5 to 6)
