Hello..I am definitely not an expert like some here but I can surely say it's not normal and very strong possibility it is an deficiency ..especially the top leaves being yellow and all...hopefully someone will diagnose this for you properly...also take a look at a deficiency table and compare them to what you might have lacking...iron , Mg , zinc , calcium....I'm not experienced enough to identify exactly what ...but it is lacking something..hope you get it dealt with soon bud

Are you growing in soil? The yellowing leaves are pretty common during this stage. In my soil grows I usually add some nitrogen to combat this. I prefer my plants to look green and healthy till the very end.
Sorry, I see it is in hydro now. Still the same advice though.If you are only using bloom nutes, add some grow formula. I usually use 50/50 bloom and grow right on through flowering to prevent yellowing.

okay looks like nute burn. whats your ppm at? i would lower the ppm. im thinking to much nitrate. right now you want more P & K with little N adjust it.

yes dont have a ph meter that is off and you dont know it. like i did and had to do an emergency ph change made my girls all mad and pissed at me. all but 2 the c99/1 blueberry they just dont give a shit they just keep growing and loving life. good luck ask and do do what the first person says unless you see he has several grows under his/her belt.

My ppms are right around 850! And I have very little nitrogen in the bucket

what is your feed mix? if it has 0 nitrogen add a little doesnt take a whole lot. also right now they really want P/K nutes. you have a ways to go till harvest so try and get them what they need. they are using almost max p/k right now. lets see what a few others say.
edit they are jsut finishing stretch also so yes give them 200 ppm nitrogen

I'm using GH micro which had 5% N at 4ml per gallon and using GH bloom at 18ml per gallon and that has 5% P Nd 4% K

How do I know how to measure 200 ppm of a nute?

what is full dose of the N? take that and cut it in 1/8 that should be close.

So you think 200 ppm of the micro which is 5% N would be good?

So how long do you think till her leaves turn green again?

they wont very much. the damage is done. she is going into bud making mode and will focus all energy on them. also make sure you dont have any light leaks at all.

No light leaks ... But if the damage is done and she won't restore then why add more N ?

so it doesn't get worse she is still stretching.

That's crazy she's still stretching after 37 days of 12/12

And do you still think I can get some fat buds even though I have this N problem?
