buds dying/brown day 58 flower

[Guest]

A few of the more sativa-ish strains i have are turning brown where the hairs come out. The reason im posting is because my purple power (which i thought was turning purple, was infact dying) already went through this, and the top cola and a few smaller branches died. Turning to like a dead crispy yellow bud that crumbles away when touched. its almost similiar to what my plant looked like when it was too closed to the HPS, and burned. but other areas around the dead parts are still alive. and there is no burn marks on the bud.

1000w hps, temps 70-75 degrees. strain: white widow. On the 2 plants in question, I think it is possible I missed one feeding by accident. I cant really remember. in the span of 4-5 days of not being fed, just watered. could not having any food have killed the buds?



pictures of some of the brown/purpleing







some of the top nug, cant really see too much here. just adding these in for extra overall pictures for people to see that not everywhere is affected.

What is the RH% of your grow area?

 

[MTF-Sandman]

How about the details of your nutes, PH, enviro & setup? There's a handy form in the sticky in this forum titled common sense usage of the infirmary :wink:

i added some of it, didnt thinkn the rest was needed.

5 gallon soil bags, ph was 6.5. AN sensi bloom 1part and bcuzz flower. RH = room humidity? if so, probably really high. i think 75% last i checked.

" RH = room humidity? if so, probably really high. i think 75% last i checked."
75%!!!! That is way too high!! That will cause problems with the buds.

 

[Guest]

crap, ive never really had a problem with humidity. so i want low humidity during flowering? what does high humidity do to buds? bud rot? i thought low humidity was bad. but i dont know i guess i had it the other way around.

Summer is approaching and its very humid during this time in florida, ive never had plants flowering during this time. can you or anyone else fill me in on the whole humidity thing? im going to do a forum search as well.

over 40% RH and you're looking for bud mold.

Your humidity is high and very well could be contributing to your problems.....but my guess would be your either overfeeding or underfeeding them...then again they may not be feeding from the humidity being so high... 40-60% is fine with light air movement......they look like they are locked up one way or another.....too much flower boost will do that too....push em too hard thinkin your helpin and the plants start crappin out in the last few weeks....some strains need heavy doses of nitrogen in week 6...IF your a super light feeder...then they look starving......your so close to the end.......depending on your situation ...it looks like its either water with straight phd water or feed....

good luck

I don't know what strains you're talking about Van Grow but I would disagree with high doses of N in the 6th week of any plant. Nitrogen during the stretch from flowering is important but by six weeks in you would be wanting the N percentages to be depleting. Are you maybe talking about a long flowering sativa? Like 16 weeks?? Sounds contradictory to the standards most abide by. If the common average flowering strain is overly N deficient towards the middle of flowering, it's because they proper adjustment wasn't made during the stretch. Keeping that N a little higher than normal flowering N rates, during that immense burst of growth(that is associated with the onset of 12/12), can take you through to the end or close enough to the end that significant N deficiency is no longer going to affect the plant. I do however agree that different plants can differ in what they need. My Mango was fine with my above way of dealing with the stretch. My Widows however, were not happy and wanted more N to be happy because they had excessive yellowing by week 5 or 6. I will be able to avoid that this next time but it will not require any added boosts of N after 2 weeks or so into flowering. I think too many people automatically switch to the bloom formulas(with low N) when they flip to 12/12. This is just an opinion as stated below. I have no formal training in the growing of or diagnosing of cannabis plants. I do know how to smoke the shit though!!

I would guess poor ventilation, since that happened to a friend's plants, but only the ones to the side furthest from the fan. If it's 75 degrees with regular watering I'm baffled.

But don't clip off the dead buds. Just harvest the normal ones and leave the dead, because a, uh, friend, had some buds die off because he was waiting for the trichomes to turn and they never did, but over the crispy, "dead" buds grew the best part of the harvest: extra crystally, all around better looking and smelling bud. That is if you have the time and space for it.

 

[Brian1975]

Dead buds?? We are talking about mold and rot and things you definitely don't want to leave lying around with unaffected bud.

 

[VanGrow]

Leaves are falling all around,
Its time I was on my way.
Thanks to you, Im much obliged
For such a pleasant stay.

But now its time for me to go,
The autumn moon lights my way.
For now I smell the rain,
And with it pain,
And its headed my way.
Ah, sometimes I grow so tired,
But I know Ive got one thing I got to do,

Ramble on.......................


But seriously....
"Brain" I think you missed the message i was trying to convey... it was laced with sarcasm although still trying for whatever reason to be positive.....BECAUSE as stated by MTF above and to all the others who need help in here....AND as said in the start of every thread so many times before......... you need the pertinent info to make any kind diagnosis....other wise its like.....why bother .....

the plant in question was right next to my intake and exhaust. I have an intake on both sides of the door. and exhaust in the same spots but about 5 feet higher. I am going to assume it was due to too much flower additives or not feeding enough, i think i skipped feeding it for about 2 weeks and gave it just ph corrected water accidently.

I have looked at some bud rot pictures and seen mold close up, but this definently either either of them. the bud is crispy brown and crumbles when you squeeze it. ill take some pictures in a moment

 

[Guest]

sorry not the best picture, one of my friends cut the majority of the crisp buds off.

Sarcasm laced growing advice, what a new and fresh idea that is. It's Brian, by the way.

 

[VanGrow]

ouch

 

[Brian1975]

Pack a bowl and we'll call it even Van Grow.

 

[McDonald]

Ive got a plant that looks exactly like that an im woundering what to do with it?

 

[abuldur]

mold

mold

man this is mold ,way to much humidity!
40% is good while flowering.
Concider buying 3 fans (for best results) and dispose them in a triangle arround your grow space (never had mold since i've done that).

PEACE

ok, maybe im really high right now, but all i can see is alill browning and yellowing of the leaves. which im positive is not cause why high humidity. plants can grow in high humidity just fine, you just run the risk of germinating any mold spores which got trapped in ur buds along the way. It is def better to keep the humidity around 30 percent to be safe. Now what i see in your plants is it could be fert def. of fert burn. like somone already said, its tough to tell. i would suggest reading up on calcium defiencies because calicum can cause blossom-end rot. which sounds like something you had in a previous grow. I would take more pH readings and really try and get it honed in so you know its got to be something else. If you do have moldy buds, you can always save them and make hash....so its never a total lose.
