Yellowing so soon might be a salt build up have you flushed ... ?

Check your run off PH and EC

If they are higher then your feeding them you got a lock out and will need to flush once you have done the flush make sure you test the PH and EC again

Let the Plant dry out for a couple of days and then start your next feed at 50% - 75% - 100% over the next 3 feeds

To keep this problem down Feed your plants

1 - 100%
2 - 50%
3 - 100%

And make sure to check your run off every 2 weeks just to make sure there is no lock out of build up
The Leaves that are yellowing are not going to recover leave them on there till they fall of or look dead but the rest of the plant should recover fast

Just make sure you keep a eye on that run off when you think everything is going sweet that's when its the best time to look salt build up is a prick and your plants will look great one day

then next time you see them they look like shit

FLUSHING! I like to flush with food at 25% and keep flushing till the level is the same or very close but that's just me each to there own

Anyway hope this helps good luck

Few indicas take 9 weeks to finish flowering. I harvest most of mine between 6 and 7 weeks at 12/12. From what I can see from the picture you have quite a few yellow fan leaves. After 5 weeks I make a point of squeezing a large bud every day. Gives you an idea of how fast the buds are maturing. Looks like you have a major grow going.

Good luck, BigSteve.

How would one check their run off for lockout or build up?

no if the run off is higher then the feed you just fed it then its lock I think if I understand it correctly

I think a better way to say it would be that an increase or decrease in PH runoff compared to nutrient solution, proves that the nutrient solution and soil medium have varied free hydrogen activity. This is what pH measures pH=-log[H^2]. That said, the results can be a piece of evidence in the theory that there is nutrient lock up, due to pH, kind of...but that's another post. Also remember as a side note that PH doesn't necessarily adjust in a linear fashion. I.E. 1 gallon pH of 7 plus 1 gallon pH 6, does not guarantee pH 6.5 but a linear approach will get you pretty close.

Basically what I'm trying to I say is that a pH discrepancy can be a sign of or a clue to the fact that there may be a deficiency, but it does not automatically prove it.

Haha, I'm not high and had to read that a few times. It makes sense. Growing is already complicated enough though. I think I'll stick with the thinking that if the ppm runoff is higher than the feed ppm then there may be a problem. :)

I'd be happy to help but you'd need to post a good picture of the yellowing you are discussing here. The HPS spectrum is deceptive. I looked at your journal and all I can say is Magnesium is an immobile and it shows at the middle of the plant not the top and I was not sure what you were referring to. So post up one here and you'll get pointed help. Also let us know your substrate etc.... all in one post.

Ok I had this argument already with someone else in another time and place but it seems to keep repeating on me LOL. If you really want a sledgehammer to put you to sleep take a Kush 15 weeks and get back to me. Really truly, just try it then tell me I'm full of it :)

You don't think the non-linearity might have anything to do with the fact it is by definition a logarithmic function :) Oh gawd.. that's a howler :) (sorry I'm pretty fucked up so I hope it's as funny as it sounds in my head, absolutely zero offense meant).
