Leaf deficiency (Pics included)

Hi these are 3 weeks old an EC 0.6 PH 5.8 under 18.6 veg light.

just this last few days these marking have appeared on the leafs does anyone know what could be causing this.

you have plenty of leaves, no defficiency there.

Not see the redish brown parts starting to form on leaves just getting little worried might be start of something that's wrong.

If anything it appears to be the start of cal/mag deficiency but could also be from EC levels.

What kind of water do you use? What is your EC? How old are the plants? What type of Medium? pH?

It's early so more questions then answers.

regards,
