Hi, I tried to Google something but couldnt find anything. I switched to flowering almost 2 week ago. After that on 2 plants leaves started to curve, become dark green and fall. Almost every new leaves that are growing are growing immedietly like that.

What medium are you growing in? Do you know what temperature your nutrient solution is? It's almost impossible to tell from that picture, but if I had to take a guess, you might have pythium? Can you see your roots? If so what color are they?
 
I was actually afriad thats it is root rot. Im growing in coco coir. Roots have brown color but I wasnt sure if its root rot or from coco coir.

Im using plagron coco basic nutrient. Soil temoperature is 23, im tent its 27. But im not sure about my tester for Soil.
 
Well i was watering more and this shit started happening so I was afraid it is some nutrient toxicty or just owerwatring so I decreased watering. But now im not sure if its root rot what should i do. I did some research and it looks like they are done

The roots turn brown and die off when they aren't kept wet and are exposed to air and light.
 
So you dont think its root rot?
Do you have any picks of the entire plant?
A quick way to tell that's pretty accurate is by gagging the PH in the RZ. What ph are you feeding?
Feed until you get runoff, collect the runoff, and tell me if the PH rose, dropped, etc, and by how much.
Do you have many fungas gnats, or bugs coming out the bottom of the pot?
Any pics of the entire plant?
 
My tester is showing pH 7 but I think its bs. Its constantly showing 7 and i was reading somewhere that cheap electrode meter can suck so I should get drops but sadly couldnt find out where to buy them

if you sniff at the roots, does it smell foul at times? I'd use H2O2 as preventive and to break-down old roots
edit:
nvm I dont think its root rot after looking at the other pics the new growth is coming out ok
feed them a little more NPK

And you shouldn't let them sit in the drain, but throw the drain away and also make sure to get the old nute solution out if the pot consistently with the waterings
Usually these "airpots" guarantee better root system internall but yours are now inside the drain... some claypebbles as drainage would prevent that next time
 
I dont understand how to get old nute solution out. Im keeping water 1 day in bottle then i water at 7am 3dl to each plant so it doesnt over water if something go to drain i will drain it with sponge. After coming from school im watering 2 or 3 times before 7pm when i will turn off Light.
 
roots grow where moisture is but die off when longer dry... google "drainage"

when you feed mineralically what's not eaten by roots could accumulate to create salt-stress over-time so you give 20% more water than is necessary to fully saturate the pot. that makes the old nute solution drain out you throw away
"drain to waste" it's called
