Leaves Yellowing 4 Weeks into Flower (N defic., normal, or something else?)

Do you guys think I need to add some N or this yellowing normal? I think it might be a little early for yellowing leaves.

Soil/perlite mix
Used recommended dose of Garden Club Select Organic all purpose fertilizer (10-2-8) when I transplanted (maybe 4-6 weeks ago) which says it feeds for 3 months.
I also added recommended dose of bone meal (0-10-0).
On the same day I took these photos, I top-fed with a light dose of Fox Farms Piece of Mind Fruit & Flower fert (5-8-4) and watered with a molasses mix.
Watered by rain, 2 or 3 buckets of well water during dry periods - I haven't tested pH this grow

Flowering began about 4 (maybe 5) weeks ago. Strains are Skunk #1, Cole Trane and The Church.
The yellowing starts at the bottom and continues to progress past what is seen is these photos (taken Aug 30th).

Any help or comments are appreciated. Thanks!

Thanks growace. Buds are chunkin up nicely now. The leaves that were changing yellow are now falling off and it's moving up a bit. I'm guessing our heavy rains this season flushed some of the nutes out of my soil. I added a bit of my original all purpose fertilizer, but it's gone now. I might try to add some more N soon, but then let them go for the last couple weeks.

i believe the term for that is called `leeching` which causes yellowing in the bottom leaves. there has been some work done on this, interesting reads. cant help ya with any links cuz i never bookmark, but you will find it....i think....

sorry but the yellowing of the bottom leafs is not 'normal'

your number one priority needs to be keeping all of the leafs perfectly healthy and green. That is how you get big buds.

uhhhm.....nowheres have i read 'If you got green leafs, you'll have big buds.' I dont quite think it works that way. Plenty of people have had yellowing occur and still have bumper crops. If you have only grown 3 times, then I doubt your experience and knowledge goes that deep. Lack of nitrogen, and leeching. Look it up dude.....note how he said his buds are chunking up nicely? .....i rest my case

there are many misconceptions about how to get big buds. using the super expensive "snake oils" as Uncle Ben would put it is not how its done. it's just biology. There are 16 elements that the plant needs. You feed them in the right amounts, keep your foliage green and healthy, and you'll get the biggest buds possible. This can be done using $10 worth of ferts.


If you're half way through flowering and you start to notice leaves turning yellow then you need to switch back to your vegging food.

I just foliar feed a nitrogen dose if they seem to yellow too quick during flower and it does the job. 2 doses in a week is all I usually use to get the girl more green

Thanks all. I realized that my dose of Fox Farms flowering nutes (which do include some N) was way too low. I beefed up to the recommended dose and things seem to have stabilized a bit. I like the idea of foliar feeding some N. Guy at the hydro shop told me plants will only take what they need (and no more) from the leaves so you don't have to worry about burning them. I didn't have any soluble N nutes or I would have tried it. Probably the best solution in this case if you can keep the spray away from the buds. And my version of "chunking up nicely" is pretty relative since this is only my second grow. I'm just glad they're alive. I see other photos on here and my buds are nowhere near that large.

Thanks for all the input and healthy discussion. I'll rep those with helpful posts.

I know you figured out what u needed to know but one thing it's not all about what lvls your nutes are at if your ph is off make sure it's around 6.5 for soil. If your ph is off it will lock nutrients especially nitrogen and your plant will dwindle or yellow. Big buds are achieved with 3 main building blocks; good supplement or high co2 which is what your plants breath; nutrient rich water ph balanced solution; and intense light; and of course your environment should be 85-90F, humidity 40%. etc... Goodluck,Oregon the chronic state.

If you haven't ph the water most likely thats your problem. Your ph should be about 6-6.5 for soil although I use 5.8-6.2

what you see is one plant

I seen your post and wanted to suggest if you do not have co2 get a burner or tank with regulator and run between 1000-1500ppm and your yeild will increase by 35-50% if your environment is correct; 85-90F,40-50% humidity. That plant could do a pound,i've seen plants that size produce over a pound,but it was in the hydro. Your strain is meant for weight it's more sativa,big bud strain. I love seeing those monster plants,goodluck. Oregon the Chronic state. I'm HHHHHHHHHIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIGGGGHHHHHHHHHHH

nah man yellowing and the loss of SOME older big fan leaves in flowering is normal because the plant doesnt focus on nitrogen consumption, it likes the P out of NPK. although you still do need N, just not near as much. P is what stimulates the flower growth. your lady is looking good man good luck

Thanks everyone for the continued inputs. Adding more of the Fox Farms flowering nutes seemed to help. I looked under the microscope and the Cole Train is just about ready. The Church shouldn't be too far behind. I highly doubt I'll be messing with CO2, especially since this was an outdoor grow. I didn't really water, just rain from above. I've pH'ed my well water before my last grow and it was pretty good (6.5 - 7) so I didn't bother checking this time, especially since I barely used the well. These plants were kind of small since I germinated in June. I started out growing on my back patio and wanted to keep them small. I found a better spot and next year I'll start sooner so they can veg longer.

Temps have been 85-90 consistently, but our humidity is way above 40%. That's why I chose The Church and Cole Train, since both are mold-resistant.

Thanks again everyone. I'll be posting harvest pics soon hopefully!

If your leaves are getting enough light,co2 and the "right", amount of nutrients your leaves won't die at all or yellow,this is normal. When your plant is deprived nitrogen and yes your plant "needs" it, your leaves start to yellow,because nitrogen is what keeps your plants green. Trust me your plant(s) do focus on lots of nitrogen consumption just not as much as others,but that does not mean that it is not equally important. If you can keep all your leaves from yellowing or dying unless you specifically want them to die then bravo keep up the good work.
