How much runoff are you getting when you feed ? Looks pretty dry around the edges of the container. I don't think it's a virus. Give it time don t overreact and start trying to fix what's not broken. New growth looks fine. Moving plants in and out is not really a good idea, especially if it's not done correctly. Mimick the day night hours . And definitely not good for flowering

the pot was out and the temperature was very hot (30~32) so i was irrigation every two days
after it stains on the leaves brought the pot in the growroom and supply light with LED (about 1 day ago)

With coco you want at least 20 % runoff every time, or you will get salt build up.

Bump the nutrients up your not telling us your ec and definitely water to runofff every time

i use double distillation deionized water so i'm not worry about ec
on each irrigation it's more than 20% about 25%~30% runoff

i'll take picture for next few days

Dolomite works well, though slow acting. Most Ca/Mg ratios used by growers are between 2/1 to 5/1, not 1/1. Less mag during veg, more mag at peak flower. I'd also suggest using a 30x or higher microscope to inspect your plants, there's some speckling on your leaves that could be indicative of a pest attack, which in turn can cause what looks like a Nute def. Good luck!

Hi
Too much nutes I think.
Wash them and don t feed to much when they are small.
Big up
