I have a small grow area 20x20’. It’s very difficult to keep humidity low during the winter. Outside temperature last week was -25 Degrees. In the flower and veg rooms the ceiling can drip on cold days. I do use 2 de humidifiers but they can’t keep up. Anyone ever have this happen?

So i need some more info.
First off do you know your soil PH?
Second. You stated its in flower? If so what week?
Third have you inspected for pest?
First glance im thinking, either Root rot. Or possible Phos defficency. Just a guess. the other info will help us to figure that out.
If you are far enough into the flowering process. The leaves will beging to consume themselves. This is usually light fading, upto the leaves basically burning up. This is pretty normal and most growers push the plants to this point every grow.
You also indicated flushing and all kinds of extreme reactions. When i flush ( which is very rare) I also add some light nuets into the plant. They will be starved otherwise. Causing early deterioration.

Looks like low humidity or too cold.Its hard to tell with out stats. Temp , humidity, indoor/outdoor, medium, fertilizer and rates, what pesticides you use, ect. include as much information as you possibly can.

To better understand your situation, I have a few questions.
What is the low temperature in your grow reaching? What is your highest humidity? What’s the output of your dehu’s? How much are you irrigating?

That looks like wind damage to me.? Fans blowing on them?

While we are all shooting a bit in the dark here, I’m happy to take a guess as well.
This looks like an overabundance of potassium to me. Usually phosphorous leaf burn starts at the tips and works inward. Potassium burn happens randomly around the edges of the leaf like I’m seeing here. When there is a deficiency they will begin to turn yellow and spot as well. These leaves are green, perhaps too green, which is a sign of something excess to me.
One could debate that an overabundance of potassium could also be a deficiency in phosphorous, calcium, magnesium, iron, and/or zinc.
What are you currently feeding these plants and on what schedule? What medium is this growing in? What are the pH issues you are referencing?

Impossible to say but, judging by how white those spots are from fertilizer over spray, it could definitely be a case of nutrient precipitation causing lockout or just too strong a mix. Nutrient precipitation is common when mixing fertilizers from different companies. The reason companies make A and B mixes is so that you avoid precipitation in storage and when mixing. That is to say, if you mixed B then A instead of A then B you’ll get precipitation. If you mix different fertilizers a chelator, like fulvic acid, can be used to prevent precipitation. What’s your ec/ppm of your feeding waterings? Microbial infection can also lead to these issues but I’d rule out all possible nutrient issues first

use only fox farm nuts. i know what you are saying about mixing, say a first b next, those spots were on bottom leaves where i poured ferti. out to fast . mix 1/2 of what says on bottle, some leaves the whole leaf looks like brown paint overspray, very small spots at first, some dead places looks like a caterpillar been eating on them.
