Hey, some of the leaves have turned yellow n some r starting to... Iv got 5 plats in my tent, only one of them has their leaves yellowing, it has the smallest pot. The others have big ones.

The plant in the small pot grew faster than the others, then all of a sudden it stunted n the others caught up n passed it, as well as the leaves started to turn yellow.

its 5 weeks old out of it's 12-13 weeks life span.

I don't know what idk means next to Ph, but I'd agree with Indica about getting a Ph meter. Are you feeding calmag and other nutirents? It looks like they need some calmag at least

Get yourself a PH meter and Ph to 6.5 and these problems will stop.

Some plants don't show a lot of signs that they are not effected, especially not right away but you will notice root/plant stunting slow growth and so on.Due to the fact they are locked of out, root damage is also inevitable.

What's your medium? Have you feed them at all? Look hungry to me.
