Overwatering or something else?

Hello

So I just transplanted 4 plants into my new modular scrog setup and 3 of the 4 are coming along spectacularly however this plant is really struggling. I believe it is overwatering from my research but to be quite honest the weird discoloration on the leaves is throwing me for a loop so im not entirely sure due to the fact that this is my 2nd grow so i'm still a little clueless. Any help you all can provide would be much appreciated.


Thank you

anyone got an idea?

Flower or veg? and looks like it needs to dry out a while looks overwatered as you said, also get some more light on it the lighter green the better

pic one is weird. the others look like over-watering.

It is in veg and just got repotted into FFOF.
