Mould on leaves 2 weeks from harvest

Any body know if it is possible to lower humidity with out a dehumidifier? And also any tips to dealing with mold on the sugar leaves?. If looked closely in the colas and can't see any mold in them but I am worried about it spreading in the last couple weeks and during drying.. I have been trimming the moldy leaves as I am find em but more keep popping up, its only a few here and there but still am worried. Any advise greatly appreciated

Intake/extraction can help lower humidity, also defoliation can help big time.

Thoroughly inspect the plant and remove anything with mold or WPM.

Sorry.. first time posting and realize I should have put more info.. I do have an extraction fan running, extracting air out of the room. But, I only have a normal, stand alone fan just blowing air around inside. Would I be right in saying an inlet fan bringing fresh air from outside the room lower humidity?

What's your temps and humidity man??

Temp is just under 25 Celsius and humidity is right up around 70-75

On a rainy week I had to put 3 bags of cheap paper towels around my girls on the last grow to get it down because my heat exchanger had quit and was waiting on a part to come in that worked out well for we at 77 degrees Fahrenheit your humidity shouldn't be that high anything wrong with your exhaust unit man??

Cold air will help lower humidity. Get some air in there.

Got pics?

Here dude here's a chart that every grower should have it helps keep our mind on track, at less it does mine when it's kinda cloudy up there in the gray matter...

I do not think so.. when I place my hand on the filter I can feel it sucking air in and on the outside can feel plenty air being blowin out. Room is, not completely, but close too sealed. Had a problem with bugs at the start. Placement could be an issue.. it is up high but on one side, and about a meter back from the plants, apposedto derictly above them. Would that make a difference?.

before I installed the extractor fan I had mad condensation on walls and ceiling.. now that is gone but humidity still way to high... might give the paper towel trick a go until I set up a full proper inlet fan set up

None that are useful for this. Only photos of plants

Funny thing is. I have 3 sativa's in there that are quite tall, and one indica (unknown strands) which is half the size of the sativas. But it is only the indica that is effected.

Where do you live bro? What is you RH outside the tent and also outside the house?

My first grow.. and know now that I should have lollipoped them to get rid of the larf.. have read that it could hurt the plant to remove larf now. Does anybody disagree with this??
Have dropped the light like that to try and hit those mid buds. Was a bit of a stich up having sativas as a first grow hahahaha but have learnt alot let them veg too long and now they are 6foot and my lighting is not the greatest.

You deserve thumb up for being brave to grow in this environment, but for next run you should really work on it. Clean it, sterilize, run sulphur evaporator before you start, get rid of mold on the walls, painting them and prepare them nice place to live. Dehumidifer will be your best friend since you do not want to grow for mold and rot. If your outside RH is high exhaust fan wont help. You can get good dehumidifer for 140€, avoid the cheap and week ones, you need at least 20l/day. Good luck

Is your excraction fam going at night too?

Also if your night time temp drops too much is can cause condensation.

Adding a heater could help.
