Read Me First
Hey guys, im surprised something like this hasn't been posted before but better late than never. I know i don't make policy around here, but i would think everyone will agree with me on this. It's very hard to diagnose a plant when you don't have all the information at your finger tips. If...www.thcfarmer.com
"Soil Growers:
1. Are you growing from seed or clones?
2. How old are your plants?
3. How tall are your plants?
4. What size containers are they planted in?
5. What is your soil mix?
6. How often do you water and what type of water do you use?
7. What is the pH of your water?
8. What kind of fertilizer do you use and what is its NPK ratio?
9. Do you foliar feed or spray your plants with anything?
10. What kind of lights do you use and how many watts combined? (HPS, MH, fluorescent, halogen, incandescent "plant lights")
11. How close are your lights to the plants?
12. What size is your grow space in square feet?
13. What is the temperature and humidity in your grow space?
14. What is the pH of the soil?
15. Have you noticed any insect activity in your grow space?
16. How much experience do you have growing? "
I have two fans. The powerful fan below, blowing directly to the plants, and I have a fan which when it blows, it intersects the airflow of the other fan so the wind is not as strong. And I have a humidifier tower in the middle which blows directly up so it can also help reduce the power of the strong fan and also increase humidity near the plant area. Also I have a small visible mist humidifier next to the plant as well. So humidity and air is being blown to the plant. Is that a problem or is it fine?Looking a like some transpiration issues. Most of the spots are at leaf edges and where they are touching other leaves and moisture can build up there.
Do you have a fan it? If not that's probably a big part of the problem. Leaves should be dancing but not the stems.
I would try to bump the temps up to 77-78F.
Do you have a PH meter?
Is your supply water tap or other?
Do you have drainage holes in those buckets?
Is it getting worse day by day? If not then it's nothing I would worry about as the leaves will not repair themselves.I have two fans.

Bump up the temp to 77 -78F in the grow room or where the plants are? Because the grow room temp is already 77F. The temps are a bit lower where the plant is (~73F) and so that’s why I’m using an additional heater.
I do have a pH meter (Moisture, Light, pH) but the pH function isn’t working properly so I just test water with pH strips, and the soil with test tubes. I use tap water and fill my water filtering pitcher and then I give them the filtered water. And yes, the pot does have drainage holes even though it takes several days between waterings.
I ideally you want leaf temps of about 75F. Leaf temps are usually 2-3F cooler than ambient temp due to evaporative cooling (other things like IR can affect it but that's another topic). So you would want 77-78ish where the plants are ballpark to achieve that leaf temp.I have two fans.

I drew a diagram for better understanding...

I bet if you keep an eye on her them patches will only increase in size as the leaf grows, it'll just be the same mark getting stretched out as the leaf grows. the patches are probably old damage.Ummm I just realized something. I took a look under the leaves and those white spots I have look like a cal and mag deficiency under the leaf. It’s just brown, dry looking spots. Could that mean it’s suffering from a deficiency?
The spots affected will die off. What i mean by getting worse is if its affecting new leaves. I agree with others this could be an issue from before. Sometimes it takes a while for symptoms to show or become noticeable. If its happening to new growth or affecting other leaves then its an issue.Ummm I just realized something.

look into what kind of (water) filter you have and how well it filters out calcium and yeah you may need calmag but like he said, id still wait another little while.Ummm I just realized something.
