Some herbicides do that.. add some micronutes with zinc. Best guess. Keep your pH in a good range.

Actually I Just looked at my pictures when i bought the 150W HPS and it was sept 1 I bought it. So they have been 12/12 for exactly a month. Today I get my 600w.. which should speed things up nicely
So I should harvest on Nov 1 correct?

don't add cal mag if they are close to done. add it to your nute rotation for next time. just a little bit, maybe 1 tsp per gallon. get a good one with micro nutes too if you can. plants need all sorts of weird shit.

i could be wrong here too. i don't know what kind of micro nutes are in those nutes you are using.

not too sure if cal mag is the answer, but if you look at the flora nova feeding chart it is recommended, so it could be the case.
