Hard to tell in pictures, my best guess is 2…Mold or Magnesium deficiency. Hoping for the latter. I’m a new guy so going to follow and hope to see a Pro stop in and put in 2 cents.

I skip the last feeding and just gave her pH’d water at 6.5. Thinking it might be nute burn.
In my opinion that looks like phosphorus deficiency. Probably because ph is a little high. Promix recommends lower, try around 6 or so
Is phosphorus a big part of Bloom Nutrients? Trying to learn something today lol…
Most “bloom” mixtures will be higher in phosphorus and potassium. Its definitely an important nutrient for bloom phase.
K cool! Thanks for taking the time to answer, the more info the better!
I had a good link that explained the purpose of each of the macro nutrients at each stage of plant growth. But lost it when I broke my old phone. The information is pretty available if you do some web searching though.
@Demar What size pots are you in cloth or plastic ?
Looks like phosphorus to me as well
I maintain 6.5 ph in the promix with no issues
So check the run off ph when you can
And those temp I assume are Celsius
So your temps are ok between 68-78 degrees f
I’m in 5 gallon cloth pots. @Countryboyjvd1971
Have you checked ppm of the run off I see your getting 6.4 ph out which should be fine @HJL
They look hungry for bloom nutes. Wondering if the strength of your lights are making them eat more.
What’s your in/out ppm reading?
That’s where I was heading low ppm
I think his plants might be burning up…28°C = 82.3°F
I have three plants in my 2 x 4 tent. The other two are doing fine. It’s just the one under my 209 watt COB light. I have risen that light to about 3 feet above plant. I will give her a good feeding and check ppm tomorrow as I just watered her yesterday. @DieHigh55 @dbrn32 @blackthumbbetty @Countryboyjvd1971
82.3 isn’t awful. It’s definitely warm, but not the worst.
I’d definitely blame the lights. Look at how tight that plant is. That’s a strong light in a 2x4, especially one with other lights, too. Strong lights make plants hungrier than usual.
@blackthumbbetty The hassles we go through just to grow a weed!
@HJL
Hey buddy, got a little sidetracked earlier sorry. The others certainly have some really nice grows, so I would keep their considerations in mind. There was a video posted little while back in different thread.
Upon watching it I noticed they had quite a few short videos about their products. Not sure if any of them will help, but thought I’d share.
@HJL
How 's it going buddy.? While i’m here, I got you on that list… thought i’d tell you while i’m here any to your problem.
I’m going to ask you a question and please be honest …Have these plants been exposed to cold air for any length of time ?
@garrigan62 The plants have never been exposed to any temperature below 70 degrees. I have three in the tent one under it’s own light. The girl in question is under my 209 watt COB light. The other two are under 7 LED bulbs respectively. I have not feed her since January 2nd thinking it was nute burn. I will give her a good feed today at pH 5.8 as I am in ProMix HP. I normally shoot for 6.4 but everyone here says I should be at 5.8 for ProMix. Funny how it is only the plant under the COB light. I have also moved the light to 36 inches above my girl.
