Sudden Yellow Leaves in Buds from Bagseeds! Whatsup? Can it be Light Burn?

[IceR]

I noticed yesterday that i got one plant in my grow tent where the buds on the top of the plants are yellow (buds on the buttom seem ok). I looked back at some pictures i had made before and found this started (though very small) at the outer side of the leaves about a week ago as you can see in this picture

And a close up from the top of the bud

Some information:

• Growtent 1m x 1m with 128 watt LED
• 3 plants in soil (6l containers)
• These are bagseeds so i have now idea about strain
• seeded on 30-03-2020 and moved to flower 12/12 on 15-05-2020
• Since then all 3 plants on 2ml biobizz topmax and 2ml biobizz bloom
• Temperature last 2 weeks about 22º/25º C and 50% humidity (before that 10 days 25º/30º and 50 - 60 % humidity)
• Airvent on 24/24 + ventilator

So as i am a 1st time grower have no experience, read a lot in the last months though and thought things like:

Light problem. As it seems to be the top buds but only one plant has this problem and all other plants are as close to the lights as this one (+/- 27 cm) so they should have the same problems

Nutrition: but then wouldn´t the whole plant have the problem.

Infestation: can´t see any but ok maybe they are invisible to the eye.

The thing is there seem to be so much different possible reasons and since i am in the final stage don´t want to f* up now.
Any help will be muuuuuuuuuuuch apreciated :)

hang in there it looks like it's ripening but i see your only about 30 days into flower...someone with some knowledge will show up sooner or later

Probably light problem. Maybe too close? You should also look for seeds.

the leaves kinda have a shiny glow to them like maybe a bit to much N but hard to tell could be the lighting...little issues like this is why i keep reading here..your only as good as the seed you start with sometimes but everyone's gotta start somewhere...I grew crappy pot for nearly 20yrs. b4 i got some good genetics...lol shame on me....BUT i have grown out many plants from bag seed that have blown away the sack at which it came from(thats how bad the smoke seen was here at one time)

one of his last pics, 79, shows heat damage

what's your ppm/ec and ph

sometimes we have to allow thing to progress a lil, before we can tell, "is this bleaching, nut burn, or heat damage"... looks like a lil of both, to me. now, that's a lower powered light, but I'd still check the leaf surface temp and (I'm using searchable terms for u, on purpose, because u learn more from your research, at this point n your new career path) i don't have to do a metric to retard conversion to know, even for that light... they're probably a lil close. 79? what's ur take on this

that u shat out the figures u did

and from the look of ur ladies

you're already a phenomenal grower, with natural talent, imho.

i would recommend u start a journal, here/anywhere... b nice to c another talented grower n the fold. watch out for a mod named diesel... i don't trust that midget, further than i can toss em. i think he's on pot, r something.

as 421 mentioned, check out some YouTube videos around harvest time. look at a maple tree in the fall. this, is typically what happens at the end... when u go into flush, in a few wks, your girls may look at u like u just kicked em in the nutz because they become anorexic, you are more likely than not, to c the natural colors of the fall season and it'll mean ur doin something right.

look for pictures and research on thc crystal evolution... put ur cell on 12mp plus/macro and get shots, 4-6" (not gonna translate, just hold ur dick up to em n odds r...) n post em. we'll take a look... so u can get 100 varied opinions as to how close u r to needing to flush and if you've ever wanted to c a full out bar brawl, in person... u just may get lucky.
from what i can minimally c in this picture and... based on the light u have... i didn't notice, many white pistals; even for just 4wks of flower. more pics, near n afar... we do love our bporn.

your crystals will fatten... fog... n then start to degrade, if I'm not mistaken, with more cbn ... this becomes a subjective decision, as to when to slash n burn. must b foggy... the ambering couch locks, in general and the foggy, spins the cerebellum. entirely subjective...
a very beautiful plant
isn't it
liken them to the human anatomy and functionality and as yes, it can b humorous... it makes em easier to relate to and the concepts ur readin about, perhaps more easily grasped and retained...
they wetten up.. engorge... because they want to get laid in the sesamella condition, to continue life. eloquent/endearing, isn't it

 

[SPARECHANGE]

and this way... if u have pics, now n later, of the thc crystals, you may have an easier time, next go, having a point of reference.

Ya their is SO much more info available these days...took me a few seasons of failure just to figure out that my climate grows great looking monster sized plants but not enough warm weather to finish the bloom...getting laughed at from friends for risking my freedom for ditch weed...but damn if i didnt have some fun along the way of my journey...TOTALLY agree...he did good to get this far 1st time out and it's not over until that big noisy fat lady does her thang ....don't get discouraged your well on your way to getting what you want iceR

inmate four two seven one

i know u said u wanted glazed

but they were out

will this suffice

u know i can't cook

how bout we just go for a cup of joe

before the noon raid

i heard about some new bag seed

guy

growing some killer bud

figured u might have nothing better to do

like us

so wtf

u take cream

?

oooo i just lost myshit

sorry

neg zero h2o

i must away

I would inspect the inside of the bud, and try pulling the yellow leaf off to check for rot.

 

[ChaoticNeal]

Could be a phosphorus def the bottom leafs are dark green an the leafs closest to the light are the most affected.

Also he’s in flower so it using quite a bit at this point.

Thanks guys for all the feedback, i´ll have to investigate a lot of the info that´s been mentioned here. In response to some questions:

• Probably light problem. Maybe too close? You should also look for seeds.

• 79: have checked for seeds but cant really see any (maybe just my beginners limitation and you can check on the pics below). Also why did you say i should check for them?

• PPM & EC don´t know dont´have equipment for this at the moment.
• PH: between 6.2 and 6.8

• I would inspect the inside of the bud, and try pulling the yellow leaf off to check for rot.

• Mancorn: I pulled out the 2 most effected leaves (see pics below) and have investigated them on rot (though not really an expert on recognising this) with a microscope and didn´t really see anything that looked like rot.

Going by the golden hairs on your tops, it looks like the plant is trying to finish flowering, and plenty of frost.

Almost assuredly if the sugar leaves pull off (with a little tug) that's a sign of rot. I would encourage you open up the bud and make sure the stem isn't showing any sign of discoloration or softening. I don't like to see any browning at the base of a sugar leaf. No need to chop up anything, but you should be able pull down on a sugar leaf and pull that section of bud away from the stem.

I do this all the time to improve the air flow, as a fat bud can trap moisture close to the stem. Start towards the bottom pulling each little section down and out. This will open up the bud and allow air in. You can really give the leaf a strong pull. It should rip in half before it separates from the stem.

It's completely normally for your larger leaves to be yellowing as you approach harvest, but not so much for the small sugar leaves. Pulling a fan leave here, and it's really hanging on. Even if a fan leaf separated at this area of the bud, I would open it up for a closer inspection. If a sugar leave separated I’d probably go ahead and remove that section (but I normally have more than I need, so willing to be overly cautious).

So Mancorn if i remove the effected sections can i leave the rest be (meaning will this be ok for smoking) and can this jump to my other plants which seem not effected at the moment? and how far away from harvest do you think i am

If it was mold/rot it would be unmistakable. Sometimes the plant cannibalizes sugar leaves especially if the bud has seeds.

On this picture i think i already see a lot of amber trichomes, especially on the leaves, could she already be ready for harvest?
