How often do you water?
Do you feeding/water them because they need it or because of a schedule?
What kind of soil are you using?
What are you feeding them?
What are your temps?
What is the Ph?

My friend was looking after the plants, just got it back so i am not sure of everything..
Plants are outside, Very hot and humide here atm 35c

Well there’s an issue. If 35 is the tempature, the ground may be even hotter. Are they in direct sun or under that greenhouse net?

 

[stngui]

Yes under the greenhouse but left the sides open and 3-4 hours per day under the sun

I have another one i kept under the greenhouse, she is looking really good.
So i will do the same conditions for the other two and hoppefully they will get better soon unless they have a dissease and thats what i am trying to find out

Looks like Russet mites, but I can be wrong. Do you have a loupe?

I suspect watering too often and out of room in those containers... I believe that they need to be up-potted and allowed to dry out between waterings all the way to the bottom.
