First Coco grow. Yellow leafes and purple stems.

[BernieLomax]

Hello AFN.
Im doing my first Coco grow, 3 sweet cheese from sweet seed's, in 10L airpots with coco.
My nutrients are Canna aqua VEGA A+B and Advanced nutrients PH perfect Micro.
My plants are about one month old (i think) and are showing the first buds.
But the bottom larger fans leafes are yellowing, and the stems have been quite purple for several weeks.
Does anyone have a tip on what i can do here?
It should absorb the nutes as it is PH perfect both the Canna and the micro.
But they are only getting more purple.
Is there anything i should be aware of when growing in coco?

A picture would help,but don't worry about the purple stems because this is quite normal for some strains.
