Hashyanswered grow question 4y ago
That's a hard one to tell. It could either be mold or salt build up.

Autoflowers with high humidity during night and rot, any solutions for high rh?Hello everyone, today I woke with a plant rot on some parts, that due to the high humidity it got during the night, 88% and 18 celsius.
What are the cheap and effective ways you do to prevent rot?
I was thinking of switching from 18/6 to 24/0 but I don´t want to stress them.
ThxOther. Mold

Potential bud rot?My critical cure has some of the smaller leaves near and in the buds which are starting to turn rusty brown. Is this a starting sign of bud rot? Should I cut them early?
I do not see anything abnormal under the microscope or when separating the large buds by hand. Thanks!3y ago

Harvest early to prevent bud rot?Had some issues with bud rot, but managed to stop it. But next week it will rain every day, which worries me. I have a small balcony I can place them under, but I don't know how much this helps as the RH will still be very high. About 25% of hairs are brown. What would you do?Week 10

Mold on stored coco/worm castingsHey all,
I mixed together 40L of Coco and 10L of worm castings, and left it sitting with a lid. Sure enough, it has some mold growing on the top. Can I still use this medium or should I just throw it out? (Not broke, but cheap!)
ThanksWeek 2

Bleu (largest of the 3 plants) is ~14 days behind the other 2. Is such a variance in size & rate of maturation common when growing from seed? Does LST/HST amplify the differences between phenotypes? She's so tall I'm worried about light stress. Should I reduce the light schedule?Week 9

How do I reduce humidityI have my grobox in the loft but it's got very high humidity 60-80. What's the best way to get it down to 40-50% for flowering? I already have a mini dehumidifier, 2x fans in the box. A dyson cool fan outside the box. Any tricks? Can't afford to spend mad moneyWeek 5
