Hello. This is my first post here, and I apologize for breaking the case. I was walking on the internet and I found your post, and seeing the pictures I could not resist answering.
Sorry, my english is very bad. Your problem is a little spider called Calepitrimerus vitis :

You can combat this spraying chemical acaricides like Prenteder (55% fenbutaestan). Dont use natural acaricides with this spider, because you loose your time.

Do not you see unless you use a 100x increase.
I've seen those crinkled leaves many times.
I hope you end up with those little bastards soon.
regards.

I chek every spot up and down for a few days so far with microscope 100 X and i see nothing.

It is a heat/light issue either the heat is too high or the light is too close.

its too hot the plant is transpiring

Agreed. When radiant heat is too close to the leaf, and it's very dry, it'll have to transpire faster than it physically can - resulting in those symptoms.

Only heat stress
heat damage leafs by curling up
I really didnt c happened cause the spiders so

it might just be a mutant fucked up leaf, either that or heat stress, but with other leaves in your pic being so close and not showing any of the same signs, i think not...

if any of that made any sense, good!

Hi friends.
You may think I'm crazy, but I know what I mean. This pest is widespread in Spain.
I have a grow shop for over 10 years and have seen this many times. What you have in the initial state, so you may save easily. I understand that you may believe that I dont know of which I speak, because it is hard to see the plague, and confused with many different problems.: Nutritional problems, problems with the substrate, problems of heat, pH, problems with the water .. .. I have seen many people go crazy with this pest, Until you finally see the plague
IIf those plants come into bloom with this problem, the buds dont have trichomes, pistils are short and almost black.
If I am right, the next thing will happen to your plant is that the new shoots will not grow and turning yellow. I hope not to be right, Although I'm sure 99%

Another time sorry for my bad english.

All your plants have the same problem?
Have you clones in the same grow room?

Its ok if i cut some of this leaves ?

I had a plant doing that ,but it was close to transplant and soon as it seen new soil it percked up and looks very happy now.

Hi Astavroulakis!!

How are your plants?
You're finished with your problem?

regards.
