so this is like my 5th week of flowering and thats whats left of the plant, my questions are is that normal for the fan leaves to be dying like that? should i start flushing it now? is this killing the potency in anyway?it seems like everyday i pick at least 2 leaves off that have turnt yellow and pretty much fall off..

I can tell you that, that is a lack of nitrogen... Let me guess, you switched right to flowering food right when the lights were flipped? Or your going lite on your food? Please provide as much info as possible. But basically your plant is eating stored N from the fan leaves in order to feed buds. Probably the most common problem I have ever seen in growing pot..

You're gonna hear both sides of this argument. Mine is that it is normal in late flowering but I have seen and grown green plants into harvest. Plants use up carbs from older fan leaves and the sugar ends up helping to form flowers. You can still add N now as you're into your eighth week. MB that will help. But don't sweat it and don't overfeed it

Ya you def don't wanna over feed, but just remember if all your fan leaves die then photosynthesis will slow down and your buds wont get as fat.. I agree with danny on just about all his post but yellowing this early isn't right... If you cut out the 2 week transition period at the beginning of flowering then technically your only in the 3rd week of flowering. Common misconseption
ok, thanks for the help..yeah i switched the feeding schedules as soon as i switched the lights, since flowering they were fed big bud and bud candy at the right times and they are under a 400hps..i had picked up some nitrogen called revive and have been giving it that for about a week now but it hasnt seemed to help yet..

Leaves won't turn green again but from what your using I would say that's your problem.. Big bud and bud candy are additives, "bloom boosters" Next time keep your vegg food going for about the first 2-3 weeks of flowering and get a complete nutrient. If your using advanced then I would suggest sensin bloom a and b, good shit.. But a lack of nitrogen is your problem and once you get the yellowing they wont turn green again, all you can do is stop the yellowing.

Why veg food for about the first 2-3 weeks of flowering instead of a complete nutrient flowering food for the first 2-3 weeks?
Please explain and thank you.
good question..

@add...I think what he means is people flip their light schedule and automatically flip their nute schedule as well. Feeding higher P and K to induce flowering while all but eliminating N. Big mistake. A smarter man than me wrote an interesting piece on this topic and here it is.....

If that wasnt his intent then sorry...but the thread UB started is good to read anyways...

Because most bloom foods don't provide enough N for the beginning stages of flowering.. Just look at it this way, When your plants start to bloom they are producing buds right? well they are also producing new leaves that surround the buds and with the lack of N your plant is gonna start sucking any available N from wherever it can (usually fan leaves) and that's why people are always getting yellowing 2-3 weeks into flowering. That is why I recommend higher N the first few weeks of flowering

Truth right there. Other than a dose of Bud Blood I keep on veg nutes the first 2 weeks of flowering to strengthen the leaves, they aren't going to be budding that soon anyway and Bud Blood gives them enough to store for later.

The same exact thing happened to me. I attributed it to hot spots in my soil mix.
possible, i mix up what i get from the bag first just to make sure that doesn't happen
there is a touch of growing philosophy here, i knowingly use a mildly 'warm' soil
nothing ever burns, but the occasional heavy feeder may not give as much quantity that it might of
thanks for explaining that to me..
