Deficiency in late flower

rkymtnman · Sep 27, 2023

IMO steady 6 pH in coco is not optimal.

and if you are towards the end of bloom, EC needs tend to drop in the plant.

What PH should I be giving them then dude?

Should I higher the EC if it tends to drop towards the end of boom, or is it normal for it to drop in the plant at the end of bloom?

i let mine float b/t 5.5 to 6.5 in dtw coco.

maybe i phrased that wrong: the plant needs less EC in about the last 2 to 3 weeks.

So what do you think the problem could be then if they need less EC in the last 2 or 3 weeks because it seems like a nutrient deficiency to me

post some pics when lights on for all your plants and then i'll try to narrow it down. just from that 1 pic you put up, hard to make an educated guess especially if there are mulitple issues

Why are there no photos?

I deleted them. It's okay now anyway boys I've found mold in my weed and I had to cut it out so I'm going to be chopping in the next week anyway so I can't fix the issue now. Cheers for trying to help me though. I appreciate it

I need another dehumidifier because I can't get my humidity down enough and I'm already pulling 20 liters out water out the air everyday and my humidity is sitting at 60% in late flower

I'm chopping them down in the next week because I've found mold in 2 of my buds. I had to cut out the moldy bits today and bin it. There's no way I can fix this deficiency now because in the next 7 days they are getting chopped.

yep, a good dehuey is a good investment. you can kinda half-ass it with good air circulation but i like setting mine at 40% and be done with it.

I've got Three 10 inch fans inside a 4x4 tent and I've got a 25 liter dehumidifier and I'm still struggling to get below 60% humidity. The outside humidity is 90% and I think that is what's affecting it. I would also like to add that it was the buds closest to the walls of the tent where I found the mold dude

kinda makes sense. probably the least air movement there.

60% RH in and of itself shouldn't cause mold, at least not in my experience. I've never once had my RH below 60%, and the only time I got burned was after a 18 hour power outage (95% RH and stagnant air). I struggle to keep RH below 65% during lights off.
I think the reason I've been able to avoid mold with "non-optimal" RH is air movement; lots of it, both above and below the canopy.

it was two buds closest to the tent walls that have gone moldy where there is less air movement. I guess I haven't got my fans positioned correctly? The humidity spikes at lights out and goes to 70% humidity so I guess I will need another dehumidifier to try and control it better?

More de-humidification would certainly help. Keeping the temp from dropping is also beneficial, whether through the heat generated by the dehumidifier or other means.

Should I harvest soon since I have found mold on 1 or 2 buds closest to the tent wall? They are 8 weeks into flower tomorrow

That's your call.
The problem with mold is that you may have only spotted the worst of it; by the time you can see mold, it's well-established.
It's likely elsewhere; particularly when the cause is environmental.

So I'm best off chopping in the next few days and scoping out all of the buds once it's dried?

That's what I fear also. I'm guessing it could have established it's self in other parts of the plant.

It's took me around 5 months to grow these plants out, lots of hard work and money on electric so I would hate to throw it all out.

I agree, it's heartbreaking to invest the time, effort, and money and have mold spoil the party.
You could make edibles; your GI tract is much more robust than your lungs.
You'll likely get various recommendations how to proceed, but inhaling mold is not a risk I'm willing to take.

Me neither dude. My friend smoked moldy weed before and now he dry heaves all the time and he can't shake it off.

I would hate for that to happen to me.

I'm hoping that it only spread to the buds that were up against the tent wall where there isn't much airflow and that I can harvest soon and prevent it from getting any worse.

I'm also scared that if there is any other mold in the buds it could spread when I am drying.

It's a total nightmare.
