Discoloration on my autoflower

[Hitemup]

Hello fellow growers. It's my second grow with same strain Incredible Bulk from Dr. Kipling. I've noticed this morning brown small discoloration spots on 2 or 3 leafs, but after I came back from work it has worsen,a lot. Also tips of some leafs got same spots but smaller.The only idea I have is too much heat at some point, because I've fitted some heating in my grow closet. And I gave it to much heat 2 days back. Thermometer showed max temp. 36 C. (97 °F). But honestly it just a guess.
Let me know please what do You think it is and how dengerous it is for the plant.

Hard to tell exactly from the pix, but it looks like the plant is small and the container is large? If the plant size doesn't match the container, it makes accurate watering almost impossible. Most often, we diagnose a deficiency, but the root cause (no pun intended) is more likely to be both under and over watering in alternation.

If the plant has been in the container a few weeks, you can probably stop worrying about over watering (soil looks dry on top) and just soak that puppy each time.

Overall, they don't look bad. I wouldn't stress too much, just keep an eye on them and concentrate on watering!

Thanks a lot for the tip. It might be that I over or under watered . I can't even be sure which one is it. I give her more water and will see. Cheers

Looks like it could be heat damage. Hard to say from the pics, because it also kind of resembles a P deficiency. But overall they look like they'll recover.

I don't think it's any mineral deficiency,as I'm feeding it just like I did the last one and there was no problem. But seems like it can be both heat and overwatering. I wasn't watering a lot ,but I was spraying pH 6.5 pure water on her 2-3 X a day.

Seems like the plant is recovering. Damaged is done to some leafs but the rest ist healthy. Here some more pics.

Much better pics. Yeah, that appears to be heat damage, and they usually recover from that when you fix the environment. I would say full speed ahead now!
