One day I came home and found that pretty much all of the leaves are brown. I don't know what I'm doing wrong. the three plants that look like this all had powdery mildew before. the other two plants I have that did not have powdery mildew do not look like this. Can somebody please help me I'm freaking out. Thanks

Did you spray your plants trying to treat the PM ?? And if you did what did you spray them with ?

I sprayed them with hydrogen peroxide mixed with water. It works good to get the pm off. Is it possible the PM made those plants weaker and more suceptible to heat damage? The temp got up to 85 degrees.

If you sprayed them while the lights were on, you helped fry them.

But that's just the beginning of your issues, really. That soil looks like clay. It also looks like you were weak on potassium before the other issue of mold started.

Never, ever spray your plants with any liquid while your direct lighting is on. Always spray treat your plants before the lights turn on so they have time to dry out and you don't blister the hell out of them.

That's my assumption too, just need more info to be able to confirm.
i try to keep temp from 76-82. But within the last week the temp has got as high as 85. Heres the thing though. The powdery mildew kept coming back even though I treated it with hydrogen peroxide mixed with water. So I got so frustrated with this powdery mildew issue that instead of spraying it and wasting my time and energy on that I just got mad and frustrated and cut off every single leaf that was infected with powdery mildew pretty much just stripping the plant of every single leaf except for the bud sites. I know this is bad for the plant but I'm so sick and tired of the powdery mildew I just said f*** it and cut all the leaves off that were infected with p.m. I still want to save the buds on it cuz the buds look really nice. Is it because I cut all the leaves off and still get the nutrients amounts the same is it too much notes because I cut off all the leaves? Are the plants overdosing on nutes because I cut all the leaves off like the nutrients have nowhere to go. This browning of the leaves only happened once i cut off all the leaves with pm on it. It turned brown the very next day. I also have to say that I have two other plants in the same tent that DID NOT have PM and they seem to be completely fine. I worked on these plans for a few months this is so disappointing. Thanks for any help its very much appreciated

Yeah it looks like you sprayed with the lights in, you usually wanna do it right before they come on. And they wouldn't be uptaking anything after you cut off all those leaves. The stress would probably stop them from drinking. And if you're not running co2 those high temps could attribute to that as well. Its not that you have poor nute uptake. Its that you have no uptake...I would wager.

I never spray anything ever. I only sprayed hygrogen peroxide with water outside the tent and let them dry before i put them back in the tent. That was weeks ago. Plants were fine for weeks, no spraying anything. Then i saw the PM come back. As soon as i saw the PM. I cut off all the leaves affected by the PM. The very next day the leaves and even the sugar leaves were burnt looking. 85 degrees at the hottest

Looks like stress, and potassium deficiency. The stress of cutting the leaves off and the heat combined I'm sure.
I guess that's what I'm thinking too. My question now is, what should I do at this point? should I continue to keep growing it as normal? Or should I just Harvest it now even though the buds are really small and underdeveloped? Thanks!
