Is this a problem?

This is an Amnesia Lemon plant. I have it in an ebb and flow hydro system in my stealth cupboard and it's at the start of week 11.

A couple of days ago I noticed that one cola looked different from the others and that the small fan leaves on it were all curled up and dry and came off easily. The head feels normal and is as sticky as everything else and up close it appears to be as covered in trichomes as the other heads. This part of the plant is not receiving any more light than anywhere else, nor is anything blowing directly on it etc. I've included the blurple pics because it shows that one cola looking different from the others but in normal light it appears a light brown colour compared to the green of the rest of the plant. Lol, ignore the tip burn, that was me.

Is it anything to worry about?IMG_4219.JPGIMG_4220.JPGIMG_4222.JPG

I think I see some bud rot or mold in the last pic and it also looks overfed in my opinion.
What would have caused the mold or rot? Is it reversible or should I remove the shit bits? What tells you it was over fed? The tip burn was me from not flushing the perlite properly weeks ago.

*edit* I've just done some reading on mold and rot. The little oscillating fan I had in there, died a few weeks ago but as the plant was established with good strong branches, I didn't bother fixing the fan. I'm thinking that although temp's been good, the humidity's been a bit higher than optimal and that coupled with no moving air has allowed the rot to start?

I was going by the leaf tips, but you are on top of that already. There are spores all around us. One specific spore, Botrytis cinerea, can come in contact, but will not germinate unless given the right conditions. To prevent bud rot, have good air circulation, avoid moisture and high humidity (try to have 40-50% RH), defoliate to improve air flow, the biggest colas usually get affected first.

When bud rot appears, you should remove all affected buds and if necessary, even the buds near it so that more spores do not spread to your other buds and cause more bud rot. At harvest, inspect the buds you are going to keep and ensure they have no rot (you can tell by the nasty colors and the leaves or buds fall apart easily. There are other methods to deal with bud rot after it has started, easy to look up.

I personally have bad allergies and asthma so I don't know if I would keep any of it and if I did manage to salvage any buds I would probably do a Jorge Cervantes style bud wash. The bud wash will not treat or remove budrot, but it will remove spores and some other contaminants on healthy buds.

I would agree there. Other than that, these ladies look about ready to harvest.
I grew this strain in my last grow and it was nearly 14 weeks in flower. I've been looking at this one and it's close but still lots of clear trichomes. Very sticky and stinky though (:

Thanks mate, good info. I haven't been able to get the humidity down past the high 50s% but it was the same during my last grow (same strain) and it was fine. The two differences between the last grow and this one is that I left a lot more fan leaves on this grow and tried tucking them out of the way rather than remove them and the fan died a few weeks ago, whereas I had the fan on constantly during the last grow.

I'll go and remove the affected bud now but do you think it would be wise to leave the fan off for the remainder of the grow for fear of blowing any spores around or put the fan back in there to improve airflow?

That's a tough call. It definitely needs airflow so things don't get worse, but you also don't want spores flying around. Not sure what to recommend for that. You could always harvest early.

I have a mesh cover for my intake fan to limit contaminants being sucked in. The one in the pic below was cleaned 7 days ago and is already caking up with dust and who knows what else. I wish I had a pic where I went a couple weeks without cleaning the cover. It really gives you an idea how much actually is in the air and can accumulates on your bud.

Yes you should remove every part affected by the mold, otherwise it will destroy your bud during the drying. With sterilied tools and take care of spores, it goes in the air really easily.

I have a screen over my intake and it can get pretty gnarly with dust etc. It might be worth covering it with a piece of cloth as well, although I think taking the fan out has contributed to the problem.

I just checked the trichomes and I'm going to chop it.

Thanks for the help guys

that bottom picture is definitely bud rot... happened to part of my first plants. i would throw that away, that's not smokable whatsoever.

i would also carefully inspect your other bud sites

Agree w/others, see how far that bud rot has spread. Also, disinfect everything before you grow again, including all the surfaces in your tent. Even then, this stuff has a nasty way of coming back once you have it. Next round I'd recommend treating your plants early and often with one of the biological fungicides along with chitosan foliar-as a preventive measure.

That was the only bud that was affected. I chopped the plant, even though it was a little early. Once the plant is chopped, I use my grow cupboard for drying/curing so I sprayed everything in there before I put the plant back in there to dry.
