Yellowing leaves moving up the plant: tomorrow is day 22 of flower

[JKB1989]

I have four white widow auto plants and one of them has this issue. Pictures below. I use AN nutes and I'm on an 18/6 schedule for the lights. Just fed last night 10 ml of micro,bloom,grow,voodoo juice,b52, big bud,bud candy, and calmag. I took the pictures this morning. The first three pictures are of the top of the plant. 4th picture is from the bottom of the plant. The next three are between top and bottom of plant.

If they were from seeds, there could very well be some genetic diversity causing one to finish sooner. Looks like normal fade to me, but not experienced with autos.

 

[Allen42]

Lots of variables at play. You fed that pretty heavily, what type of system are you growing in?

 

[Allen42]

It could be natural fade, or it could possibly be a nitrogen deficiency. It depends a lot on how old the plant is, what’s it’s feeding schedule has looked like up until now, etc... a very useful tool that I like to use is this

If your anything like me and those deficiency charts are hard to read, you could give this a try. I feel it’s a helpful tool if your ever unsure about your plants condition. Hope I was of some help

I'm growing in ff happy frog with 30% perlite added.

looks to be a little light on one of the macronutrients... are you using the dosage that AN recommends for this week of the grow? IMHO it is a bit early for a "natural" fade.

I have five C99 x Blueberry where one plant did that with the fans. These plants were started from seed. I started seeing this at the 5th week or so. The rest of the leaves stayed nice and green. It dropped about 85% of the fans starting from the bottom and going up. It's actually a very healthy looking plant and its turning out to be a great yielder. I'm thinking it's just a genetic trait in this plant. The remaining leaves are all yellowing a bit now, but that's because it's almost done now. Maybe this is what you are seeing.

Amilya. I actually went heavy on bloom and calmag. I'm embarrassed to say but I didnt look up the schedule for flowering and just added big bud and bud candy to my nutes at the recommended doses. Thanks so much for your reply as I'm this site a lot and I have the utmost respect for you and all you do for all of us...

 

[JKB1989]

Scottsquash... I have five more weeks left on them so I'm concerned about how bad this will get. It is only the one plant and I've done the same with all of them... so.... thanks for your input all suggestions are really appreciated...

 

[Scottsquatch]

Let's hope it's just a genetic trait. Are all the leaves doing this or is it just the fans?

 

[JKB1989]

Just the fans...

 

[Scottsquatch]

Well, maybe it's similar to what my plant did. Were they from seed or clone?

 

[bobrown14]

looks ok to me - you're doing a great job. Plants are healthy. Some plants will loose leaves turn yellow etc. Perfectly normal and expected.

 

[JKB1989]

From ck seeds

In my experience my plants also will cannibalize a few of its leaves here and there during flower. I really wouldn’t worry about it as long as most of the leaves look healthy and the plant seems to still be growing

Well the leaves are not getting better with the feeding so I'm going to flush them when I get home. Its reboot time. Question I have is when I reboot should I add voodoo juice to the base nutes?

 

[Greenlizard]

Did you flush them when you switched from veg to bloom?

 

[JKB1989]

No. I dropped the ball on that one

voodoo juice is simply microbes, and the more the better. You can't give the juice too often.

 

[JKB1989]

So to flush I use 5x the medium volume, wait an hour then feed. Following AN feed schedule for week 4 of flower.
